While immunity from COVID-19 infection after the Moderna vaccine wanes from four months after the second dose protection against severe disease remains, according to Qatar research. The team calculated the effectiveness of Moderna based on positive PCR tests in Qatar and the outcomes of the infections. The researchers say protection against infection peaked at 90 per cent in the three months after the second dose and began waning at the fourth month, dropping to below 50 per cent after seven months. However, the researchers say protection against severe, critical and fatal COVID-19 peaked at "essentially 100 per cent" with no evidence of waning during the same seven month time frame.
