A questionnaire-based survey conducted by a group of Kochi-based doctors among 5,971 adults across the country to assess the community level experience of the pandemic, with focus on the third wave and vaccination, has reported that 30% of the respondents who had taken the third dose (2,383 persons) had contracted COVID-19 during the third wave.
The percentage of severe disease (defined as the proportion who required supplemental oxygen during hospitalisation) during the third wave remained below 1% among all vaccinated individuals, whether they received the third dose or not. Moderate severity was reported by 42% of those affected during the wave.
About 98.6% of the individuals in the study were fully vaccinated. Among those who did not take a third dose, 45% reported COVID-19 in the third wave.
