Are booster vaccines the way out of this pandemic?

Vaccination promised a straightforward way out of the pandemic. Protection from TWO doses of vaccine initially promised to end the pandemic.

Israel led the way in mass vaccination. Infection rates plummeted and life seemed to be returning to normal.

But infection rates then started rising in Israel and Israel was forced to use booster vaccines for high risk population.

It is now hoped that the THIRD booster vaccines would provide a way of keeping COVID infections at a manageable level.

Only time will tell whether this strategy would be successful!

Would COVID Vaccination become mandatory for all adults ?

It is unlikely to become mandatory in most western countries. It almost certainly would not become mandatory in USA, where Vaccination seems to become tangled with highly divisive politics.

But it is not an impossible scenario in European countries.

It is possible that more countries would follow the example of Turkmenistan, which has a policy of “no jab, no job”

Also, it does not have to a direct government policy.

If the governments change the law to allow businesses to demand vaccination proof, then indirectly vaccination becomes mandatory for most people.

Private Businesses and Travel industry may decide to make vaccination mandatory for their employees and customers so as to avoid further disruption to their business.

In countries, such as Israel and U.K., where there is already high uptake of vaccination, a change in Law may not be needed at present.

But if the present surge in infections continue, and variants emerge, Governments may change their approach.

Have People died after COVID-19 vaccines ?

Yes, people have died after having COVID-19 vaccines.

Recently, a BBC Radio Newcastle presenter, Lisa Shaw was reported to have died after the Astra Zeneca COVID vaccine. Her family is blaming the COVID vaccine for causing clots and ultimately her death.

In India, a Popular Tamil actor and comedian died within 48 hours of receiving a COVID vaccine. His vaccination was broadcast live on TV to encourage public uptake of vaccination but his unfortunate death after vaccination probably ended up causing vaccine hesitancy in some people.

A news article in BMJ reports that the “Pfizer-covid-19 vaccine is “likely” to have been responsible for at least 10 deaths of frail elderly people in nursing homes in Norway”.

But, the most important thing to remember is that deaths are rare after COVID-19 vaccines.

Yes, there are true distressing accounts of vaccine side effects. But what you do not hear is the benefit most people have from vaccines.

Millions of people received vaccines so far with vast majority having no major side effects.

Consider this for context. Think about plane accidents. Millions of people travel by plane without any problems. If People fly safely and reach their destination, it is not headline news. People do not go around saying that they have traveled safely by plane and that they are alive !

But a aeroplane accident which happens rarely is front page news. It would be all over the 24 hour TV news channels across the world. Plane accidents are utterly and unimaginably devastating for those individuals and families involved. But the rare plane accidents do not make most other people avoid flying. The accidents do not mean that no one should travel by plane. The travel by planes has far more benefits than risks for majority of population.

Same with COVID vaccines. Serous Side effects are headline news even if they are very uncommon and rare. The available data indicate benefits are much greater than risks.

So think carefully before you refuse a vaccine.

Vaccine Hesitancy

Worries about vaccines are nothing new. Anti_vaccination groups were formed in 1860s when small pox vaccination was made compulsory. Even when small pox was causing untold devastation, some people were opposed to it.

The Vaccine hesitancy of 19th century is somewhat excusable. Some of the worries were real, and not much was known about the safety of small pox vaccine at that time. Lot of people were ill-informed and did not have access to good sources of information. They didn’t know the immense potential of the vaccination to eliminate distressing diseases.

Vaccines have now successfully eradicated small pox. Many other devastating infectious diseases such as polio have been controlled in many countries across the globe due to the vaccines.

Some of the vaccine hesitancy in west is because western people are not fully aware of the devastating power of infectious diseases (at least until COVID-19 came to the world in 2020).

Vaccine hesitancy is also sustained by “confirmation bias” . Confirmation bias is the tendency of human beings to seek information that confirms what they believe in. If you distrust vaccines, you go looking for information that confirms you beliefs and you disregard information that proves vaccines are hugely beneficial.

Some people wish for a 100% safe vaccine. But there is no such thing as completely risk free vaccine. It is true Vaccines can cause serious side effects. It is true that Vaccines can cause long term side effects. It is true that Vaccines can rarely cause life threatening side effects and even deaths.

It is normal to worry about side effects of vaccines. But the potential for side effects should not be the reason to decline vaccination.

One has to look at benefits as well as risks. Some people focus on everything bad that can happen as a result of vaccines.

COVID-19 vaccines had an unusually short development period. This is because of the pandemic. The available evidence indicate that the benefits of the vaccines are far greater than risks. It is true that there is no long term safety data. But in the middle of a pandemic, which has caused untold misery to millions, waiting for perfect long term data is not an option.

If you are sceptical about vaccines, please do focus on benefits as well as risks. Do not focus on risks only.

Can Vaccines get us back to normal life again during autumn?

Possibly Yes, but not sooner than that.

Perhaps in later part of 2021, life can just approach some sort of normality in western countries with high uptake of vaccination.

There are many hurdles along the way.

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 !

A first COVID infection can make the body resistant to second infection for atleast five months

If someone had a COVID-19 Coronavirus infection and has recovered from it, then their body develops resistance to a further second infection

The protection is similar to that provided by vaccination. The UK study found that the protection lasts for atleast five months.

Caveats: It is not known how long the protection will last and the study is ongoing.

While a previously infected is protected against 2nd infection, that person can still carry and transmit virus to others. PHE reports that “early evidence from the next stage of the study suggests that some of these individuals carry high levels of virus and could continue to transmit the virus to others”. So the usual COVID-19 precautions are still needed.

The study involved healthcare workers from hospitals across the UK. The study recruited mainly Young and Middle age people ; it is not known whether the study findings would apply to older age people who are the most vulnerable.

The protection is not 100%. The protective effect was noted for only 83% . So there is still a chance someone who has recovered from the 1st infection might still get a 2nd infection.

The other big concern is “the risk of reinfection from the new Covid variants spotted in the UK, South Africa and Brazil”.

The study continues and more information would be available later this year ”

Some Good news for those who have recovered from a COVID-19 infection !

People who have recovered from a COVID-19 infection are expected to have some protection against another repeat infection by the COVID-19 Coronavirus.

The protection comes from patients own antibodies present in their blood.

Previously, there was a concern that this protection might not last very long and that the levels of protective antibody may drop off quickly and this in turn can lead to repeat infections.

Now a study from Oxford indicates that protection against repeat infection (re-infection) can last atleast 6 months.

This news indirectly might also be good news for COVID-19 vaccines .

Vaccines work by tricking the body into thinking that there is a virus infection and the body then produces the protective antibodies and cells.

Based on this study, one can logically hope that the protection by vaccines can be long lasting as well. Of course, nothing is certain and further vaccine data is awaited to confirm this.

Is this the beginning of the end for COVID-19 ?

The superstitious might say “don’t jinx it by calling the end early”……..

So the answer is “may be”.

The good news from two Vaccine trials indicates that this might be “beginning of the end” for COVID-19.

Two recent press reports give rise to lot of optimism to the population that is getting weary with the lockdown. It is good to have a ray of hope among all the doom and gloom.

The covid-19 vaccine (mRNA-1273) from US biotech company Moderna was found to be 94.5% effective.

Another mRNA vaccine developed by Pfizer and BioNTech was reported to be 90% effective.

Now the caveats…. these are interim trial results and the trial results have not been subject to scrutiny by the wider scientific community as the full results are yet to be published.

Clinical Trials usually recruit motivated people without too many other medical problems. So one has to hope that these interim trial results can be replicated in the wider elderly population with lot of medical problems.

Update: Now a third Vaccine, the “Oxford Vaccine” has been found to be 90% effective when given as “a half and then full” schedule.

Update: summary so far at BMJ website.

Let’s hope that all the vaccines are very safe and highly effective when used in the real world population.

Coronavirus re-infection and immunity

Many Viral infections give some sort of immunity to the person infected. For example, if a child has chicken pox, then the child develops immunity to further chicken pox. This immunity can even be life long for many children.

But some viral infections don’t result in significant immunity to further infection. For example, Flu and Common Cold viruses infections do not result in effective long immunity. That’s why flu vaccines are given yearly to vulnerable people.

It was hoped that a Coronavirus infection could result in at least some sort of long immunity to further infections.

A recent report of man who developed Coronavirus/ COVID-19 for the second time is worrying. If this is a widespread phenomenon and not an isolated case, then it has significant implications for the current pandemic.

Herd immunity, whereby many people are immune to further Coronavirus infection either through previous infection or Vaccination, was suggested as the way of ending the current pandemic.

This report, if confirmed to be true across significant sections of population, would indicate a much more longer duration of COVID-19 pandemic.

If you survive the Coronavirus, Can you get Coronavirus infection again ?

Yes, you can get infection again.

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 !

Is Honey a better treatment for coughs and colds ?

Possibly yes, in some cases of viral infections , according to a paper published a BMJ group journal ( BMJ Evidence Based Medicine) .

The paper has been widely quoted in various newspapers today.

The BMJ group journal authors report: “Honey was superior to usual care for the improvement of symptoms of upper respiratory tract infections.

It provides a widely available and cheap alternative to antibiotics…….but further high quality, placebo controlled trials are needed.”

A word of caution: Honey has high sugar content. Diabetics need to be careful. People will allergies need to take care. Of course bacterial infections need antibiotics particularly in old and vulnerable!

Can you get Coronavirus infection more than once?

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.
