In USA, about 5800 “breakthrough” COVID-19 infections has been reported so far among the roughly 77 million people who had been fully vaccinated. That’s less than 0.008% cases.
A much more smaller minority among this minority group had serious infections. Among the 5800 cases, 396 patients were admitted to hospital and 74 patients died from COVID-19. That’s less than 0.0001% deaths.

If someone has recovered from a COVID-19 infection, they would have some protection against getting another COVID-19 infection.
But, even if someone has recovered very well from a previous infection, vaccination is necessary because there is still a significant risk of getting COVID-19 infection again.

Like everything else in medicine, risks and benefits needs to be assessed in each individual case.
For instance, a doctor won’t give toxic treatments for a self limiting flu. But, on the other hand, a doctor will try toxic chemotherapy to control advanced lung cancer.
No vaccine or medicine is ever going to be 100% safe.
For that matter, Life is full of risks. Getting out of bed can be risky. Not getting out of bed everyday is also risky.
Older adults who are at high of COVID related death and COVID related complications should have the vaccine during this pandemic and not worry too much about rare serious side effects.
But young adults, who are a low risk, can avoid Astra Zeneca vaccine based on the available data, if alternatives are available.

A recent study published in the esteemed Lancet Oncology Journal shows that the vaccine is well tolerated in patients having immunotherapy.
Unlike cancer chemotherapy, immunotherapy works differently. It works by releasing the in-built brakes holding down the immune system thereby boosting the body’s immune system against cancer.
There has been some theoretical concerns whether this might lead to COVID vaccine causing more side effects.
Reassuringly, the Vaccine side effects were NO different from those seen in people not having immunotherapy. The Vaccine also did NOT increase the immunotherapy side effects.
So the study is good news for tens of thousands of patients on immunotherapy and any cancer patient who has hesitated before, should seriously consider having the vaccine now
COVID infection could be very nasty in cancer patients and all evidence points to the benefits of vaccine far outweighing any risks from the Vaccine.

Many millions of people have now been vaccinated against COVID-19.
The COVID-19 vaccines are highly effective but the next important question is how long would the vaccines continue to protect.
Some vaccines for other viral diseases offer life long protection but others like flu vaccines need annual boosters. COVID-19 Studies are still ongoing.
A recently released Pfizer vaccine study data indicates that protection with Pfizer vaccine lasts for many months as a minimum. To be precise, so far, Pfizer vaccine was found to have 91% efficacy for up to six months. Ongoing studies would clarify whether booster vaccines are needed in future.

Vast majority of people are desperate to have vaccination and some people are even queue jumping. So this issue is of relevance to some people only and that too when vaccines are freely available to all.
If you are a plumber, who may be visiting the homes of Vulnerable people or a Care Home worker looking after very elderly people, it may be justifiable to say ‘no jab, no job’.
Balancing individual Liberty versus the benefit of others would be a legal minefield particularly when existing workers are concerned.
Furthermore, there are still lot of things we do not know how vaccines. We do not know how long they will protect somebody. We do not know whether all vaccines have similar efficacy. We do not know about the extent to which vaccines would be effective against any variants.

If all the vaccines now in use continue to be safe and highly effective in real world population, then it is only a matter of months before the pandemic comes to an end and normal life returns in 2021 !
Vaccines work by tricking the body into thinking that there is a real infection and hence the body produces antibodies. So this study indirectly indicates the protection from vaccines will also last longer and yet another reason to be hopeful about the end of pandemic in 2021.

More good news on the vaccine front in the fight against the coronavirus.
Two new vaccines have reported positive results.
The NOVAVAX vaccine is first Vaccine to report efficacy against the new variants. It is 95.6% effective against the original strain of coronavirus.
NOVAVAX is 86% effective at protecting against the new UK variant, which is very reassuring. But the Vaccine is only, 60% effective against South African variant of the virus. The efficacy against Brazilian variant is unknown.
The Janssen vaccine, produced by the US giant Johnson & Johnson, is a single-dose vaccine and has proved 66% effective against Covid-19. The vaccine was just 57% effective in the South African part of the trial.
The reduction in efficacy of both vaccines against new variants is a bit worrying and indicates that if further new variants emerge in future, existing vaccines could be less effective and vaccines would need to be updated.
The Janssen vaccine uses a common cold virus and uses a approach similar to the Oxford Astra Zeneca Vaccine.
Novavax vaccine differs from existing vaccines and it uses a artificially produced COVID-19 spike protein, which is then assembled into nanoparticles to make them look like coronavirus.

A significant minority of people have an unhealthy scepticism about all vaccines in general fuelled by misinformation on social media. Some people in western world, who haven’t seen the horrors that can be wrecked by infectious diseases, have an ill-informed view about all Vaccines.
Vaccines have played a significant role in protection against various deadly infections diseases in the past century. The infectious diseases of childhood have become less prevalent even in developing countries now. But there is a risk of Vaccine Hesitancy spreading to these third world developing countries.
The concerns of people with Vaccine Hesitancy particularly relating to COVID Vaccine is genuine. The COVID vaccines have been rapidly developed and there are no long term efficacy or toxicity data. Because it is a global emergency, countries are forced to begin COVID vaccination based on the available excellent short term efficacy and safety data. Only time can tell whether the Governments got it right over long term.
But there is no evidence to suggest secrecy or conspiracy surrounding development of various vaccines including COVID vaccines. For instance, two reports of severe allergies due to COVID vaccine was immediately brought to the attention of everyone by Regulatory authorities in UK.
It is now reported that Norway is investigating deaths after coronavirus vaccination in very frail elderly people. Any adverse report on vaccines will be investigated and made public.
It is very important to remember that life is full of risks. People make decisions every day based on benefits versus risks ( eg driving a car). People need to understand that the benefits from most vaccines against infections diseases significantly outweighs the risks of various vaccine side effects. While a handful have serious side effects, many millions do benefit from the all vaccines.
“Vaccines hesitancy” is also not helped Historic mistrust of government in sections of population which regrettably can make things difficult in terms of achieving good vaccine coverage at population level.
If you have concerns about vaccines –
“Do read information about Vaccines with an open mind and pay attention to high quality population level studies assessing risks versus benefits and ignore individual unsubstantiated stories”.
“Do speak to your doctor about your concerns with an open mind”.
“Do NOT always seek information that affirms your views and Worries. Do seek reliable information that challenges your views on vaccines before you make your choice”.

The first problem is supply of Vaccines. There are limited initial supplies globally. It will take many months even for richer countries to get their full supply.
Secondly, Vaccines take many weeks to become very effective. In clinical trials, more than 90% effectiveness was noted for some Vaccines a few weeks after the second dose.
Millions in the UK are yet to receive the first dose. Lots of people would not get the second dose until 10-12 weeks after first dose. A UK minister predicts a September vaccination target for all adults.
So it will take time for the full Vaccine effect to kick in at both individual as well as society level.
Thirdly, there is a potential problem of “Vaccines hesitancy” in sections of the society. A significant minority of people have a unhealthy scepticism about Vaccines fuelled by misinformation on social media.
Fourthly, it has to be pointed out that “No Vaccine works perfectly”. A Vaccine does not offer 100% protection. The high efficacy rates noted in young healthy volunteers participating in various trials might not be observed in real world population, and efficacy rates might be lower in elderly people.
Finally, the most serious potential risk and hurdle would be loss of Vaccine efficacy if new variants of Coronavirus are not protected by existing Vaccines.
Keep the mask; a Vaccine won’t end the COVID-19 crisis right away !

It might seem foolish to ask the question “Anything good from this COVID-19 pandemic?” when so many people across the world has been so badly affected by the coronavirus pandemic.
There is some truth in the proverb that “every dark cloud has a silver lining” and no matter how bad the current pandemic is now, human spirit and endeavour would get something positive out of it.
One possible good thing that has come out of the pandemic is the “mRNA technology”.
The successful use of RNA technology for Coronavirus Vaccines would hopefully enable the versatile RNA technology to be further developed and successfully used a cancer treatment in near future.
Further clinical trials in cancer patients would be done to provide proof of their potential.

You might have read information about the COVID vaccines on various news outlets and social media messages.
If you want complete summary information about vaccines approved by the regulatory authorities, click on the links below.
Two types of information leaflets accompany all licensed medicines. – One is meant for health professionals and has lot of clinical information. (called SPC) – The other is meant for patients and public and provides a summary of facts using lay terms.(called PIL).
The leaflets provide information about all common side effects observed in the trials.

Now the regulatory authorities have approved a third vaccine. The third vaccine from Moderna along with two other vaccines should help to bring the pandemic to an end.
The Moderna vaccine is a new technology like the Pfizer Vaccine. (based on mRNA technology).
Like the two vaccines, the short term data for Moderna vaccine is very encouraging.
Over long term, one hopes that the protective effect of all the three vaccines is long lasting and that they remain effective against any new variants of coronavirus that might emerge in the coming months.
Overall, there is certainly ‘light at end of the tunnel’ and the world can emerge out of this horrific pandemic in a short period.

The whole world is placing their bets on vaccines to defeat the Coronavirus and emerge out of this dreadful pandemic.
Studies are ongoing about the effectiveness of vaccines against this new variant coronavirus. There is a risk that changes seen in the variant virus (mutations) might make it evade the vaccine shield.
So far, there has been no conclusive evidence that the variant virus will definitely escape the vaccines. Even if they do, the good news is that current vaccines can be adapted to deal with the changes in the virus.

The guidelines indicate that anticipated benefits of vaccine are greater than unknown risks from the Coronavirus vaccines.
The Vaccine trials deliberately included lot of healthy people. Very few people with cancer, particularly cancer patients on active treatment, were included in the COVID-19 trials. So there is not much direct evidence regarding efficacy and safety of Vaccines in cancer patients. But indirect evidence significantly favours Coronavirus vaccination in cancer patients.

Long term, there are some uncertainties. For instance, there is a possibility of loss of efficacy if vaccine effect is not long lasting. But there is no evidence to suggest at present this would happen. As regards long term side effects, once more data is collected and more patients are followed up after vaccination, there will more mature data on side effects.
The available data suggests that very high groups who are a high risk of death from COVID , have good odds of benefitting from vaccine.
It may be that low risk groups such as people in 20s, who have less chance of dying from COVID, may opt for more long term data before having the vaccination.

The new mutant is more dangerous because it is more easily transmissible from person to person. The new variant is now spreading very rapidly in London and South East of England.
Emergence of this new mutant (called variant VUI-202012/01 fall) is a certainly a worrying development in this pandemic.
The mutations has made the new strain 70 per cent more transmissible but scientists do not expect these mutations to reduce the effectiveness of vaccines.
Tests are being carried out to confirm that the existing vaccines would still have a high degree of protective affect.
It is an evolving area and we have to hope that the new variant doesn’t make things worse than they are now !

After someone has recovered from a Coronavirus infection, the body remembers how to fight the virus in future. This is called immunity and it is not known how long this immunity will last.
If the immunity is not long lasting, people can get coronavirus infection again during the second and even third wave.
The body’s immunity is made up of two types of cells: B cells and T cells. T cells and B cells are central to the human immune system.
B cells produce antibodies and previously in various studies , they were found to decline rapidly give rise to fear that people would get Coronavirus infection again and again.
Now a study has reported that T cell immunity can last more than 6 months in patients who have recovered from an infection.
This news is also good from a vaccine point of view. It gives us hope that sooner or later an effective vaccine would become available.
BMJ News. Covid-19: T cell response lasts for at least six months after infection, study shows BMJ 2020; 371 doi: https://doi.org/10.1136/bmj.m4257 (Published 02 November 2020) Cite this as: BMJ 2020;371:m4257

The National Health Service had recently embarked on a Risk assessment exercise of its staff to assess the Vulnerability of individual members to Coronavirus infection ( COVID-19).
The exercise is being done with good intentions. Given the unprecedented situation of the pandemic and lack of concrete data , the exercise seemed to have steered away from firm “one size fits all” type of recommendations.
Given the uncertainties with the currently available data on various forms of protection ( from simple surgical masks to shielding) , the exercise could have been a starting point for an nationwide intervention study .
An opportunity seems to have been missed and if there is a second wave, NHS might regret not learning from the first wave.
Last month, we had studies reporting that the immunity to Coronavirus fades quickly after recovering from an infection. The scientists have warned that re-infection is a risk.
Now, we have a case in Hong Kong where a patient seem to have been unlucky to get the infection again. It is a worrying report and suggests that coronavirus is going to be with us for a long time.
The only reassuring fact is that patient was free of symptoms during second infection. One has to hope that all re-infections are mild !

If you are one of the unlucky ones to have already been infected with Coronavirus infection but recovered from it, can you become unlucky again and get another Coronavirus infection later this year ?
Unfortunately, the answer is a YES.
Some Viral infections can sometimes lead to life long immunity. For example, most people who had chicken pox as a child tend to have lifelong immunity and it would be uncommon to get chicken pox again. (except in some circumstances).
But infection with ‘Coronavirus causing COVID-19’ doesn’t seem led to long lasting immunity or resistance to a second Coronavirus infection.
A Newspaper report on a study by a team from King’s College London suggests that susceptibility to a second infection may occur as short as 3 months in some patients. This because the level of antibodies produced by the immune system after first infection start to fade away within a few months in some patients.
If confirmed, this is probably one of the most worrying news during this pandemic.
This study result could also affect Vaccine development and how frequently it may need to be administered.
