Failure of subject recruitment

Till now, mortality reports among children below 9 years remains extremely low despite that the incidence of death toll is high and exceeding 50,000 patients among older population, One speculation for lower SARS infectivity is that cross-protective antibodies against measles vaccine ( MV). In mice susceptible to measles virus, recombinant MV induced the highest titers of neutralizing antibodies and fully protected immunized animals from intranasal infectious challenge with SARS-CoV,

The primary objective of the present study is to determine the benefit of measles vaccine in health care professional to decrease the incidence of COVID-19.

We Hypothesized that, measles vaccine may lower the incidence of serologically proven SARS-CoV-2 infection and reported respiratory illness
