Contracting Covid 19 earlier doesn't mean you have a better immunity against coronavirus now

A new study suggests that the two doses of vaccination is necessary for people who have contracted the coronavirus earlier.

A new study has been conducted to ascertan the effects on a human body if the second dose of the Covid vaccine hasn't been taken.  As per the research, two months after the second Pfizer/Moderna vaccination, antibody response decreases 20 per cent in adults with prior cases of COVID-19. The study also tested how well current vaccines resist emerging variants. The findings of the study were published in the journal 'Scientific Reports. The Northwestern University study underscored the importance of receiving the second dose of vaccine, not only because it is commonly known that immunity from vaccines wanes over time, but also because of the risk posed by the new and emerging variants, including the highly contagious delta variant.
