Coronavirus Vaccine: What happens if you contract COVID-19 after taking the first vaccine dose? When should you get your second dose?

Doctors aren’t really surprised by the data of positive cases coming in after the first vaccination schedules. Scientifically, it is completely possible to get the infection since antibodies only start to peak 2 weeks after the jab is injected.

However, since these are experimental vaccines, there’s also some research to suggest that odds of getting the infection, though there may be lesser than what unvaccinated people can expect.

As per available research, all the vaccines being offered in India (including Russia’s Sputnik V) do offer some level of protection after the first dose, which may also vary depending on the individual’s immunity, high-risk conditions. A single jab of the Covishield (Oxford-Astrazeneca) vaccine are upto 48% protected and bring down transmission rates (NHS study, UK).

Similarly, as for Bharat Biotech’s Covaxin, touted to be well-effective against severe strains of the virus, the first jab could offer similar rates of protection. However, the severity and mortality rate may be on the lower side.

Anecdotal research has also showcased that a single dose-jab may be the best effective for those who have contracted COVID-19 before, as it can help boost protection and antibody count.
