COVID reinfection: Will it impact vaccines?


If there are looming fears of COVID reinfection, there naturally arise immediate doubts over how far could a vaccine probably work- if a person's antibodies or immunity aren't strong enough to ward off future infections, what hope do we have?

What does it mean for vaccine development?

There have already been constant doubts about a vaccine's efficacy, whether or not a shot would be enough to fight the pandemic.

However, even though COVID reinfection brings a lot of loopholes forward, it won't really be detrimental to the development of any vaccine right now.

Here are some reasons why:

We might require more than one shot of the vaccine

The case of COVID striking again is evident of COVID immunity not lasting for long and antibodies starting to wane after a while. But it does not mean the end of the road for vaccine work. If anything, the case for reinfection makes a stronger case for devising rules and regulations for vaccine administration like will we require a booster shot, will repeated doses be needed or not.

Isolated cases of reinfection do not make for credible proof

"It is very hard to make any strong inference from a single observation," said one of the lead experts working on a unique COVID genome project in London

The same was concurred by the Indian Council of Medical Research ( ICMR) in its latest briefing, adding that a single case cannot determine how effective vaccines are. Balram Bhargava, head of the ICMR said.

Strong vaccines are made with mutations

Most likely, any vaccine which is registered for use will be able to work to provide base-level immunization. Additional boosters such as adjuvants and antigens can work to support the working of a vaccine as well.


There's a lot of research still needed to support the dangers of reinfection. A lot of vaccines are under work and showing promising results.
