Is the new vaccine against COVID-19 causing CoronaVirus safe and effective ?

Yes, the available short term data indicates the vaccine is safe and effective in vast majority of people.

The big unknown is the long term efficacy and side effects.

Normally medicine progresses slowly and carefully like a big train turning slowly on sharp uphill bend .

But due to pandemic emergency, the vaccines are being introduced to the the general public more more earlier than it would have done, well before availability of more mature data.

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.

The trial data published so far, UK Medicine regulator conclusions , Pfizer data sheet and UK govt Guidelines has been positive so far.

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.
