Coronavirus: Is vaccine immunity waning in India? #IndiaNEWS
A recent increase in the share of the elderly in deaths from Covid-19 in three Indian locations for which data are available could be the starting point for a conversation around the possibility of waning immunity and the resulting need for vaccine booster shots, an IndiaSpend investigation shows.Data on deaths from Covid-19 by age available for Kerala, Tamil Nadu and Mumbai show that the share of those aged 60 years and above in total Covid-19 deaths declined sharply from April onwards, with this age group becoming eligible for vaccinations from March 1 onwards. The initial government-recommended gap of four-six weeks between doses of both Covishield and Covaxin, the two Covid-19 vaccines approved for use in India at the time, made many seniors eligible for their second dose from early April onwards, coinciding with the sharp decline in the share of seniors in Covid deaths, which IndiaSpend reported in May.However, data now shows that despite the curve of the pandemic being currently in decline in India, the share of the elderly in total Covid-19 deaths has risen slightly. While this increase is small, it has taken the share of the elderly in Covid-19 deaths back to levels last seen months ago, and is the first secular increase since the post-vaccination decline.
