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 !
