New York, Nov. 21 (IANS) In a fight against the new coronavirus, scientists have now claimed that the MMR vaccine, which protects against measles, mumps, and rubella, may also protect some people against severe symptoms of the Covid-19.
The study, published in the journal mBio, found a statistically significant inverse correlation between mumps titre levels and Covid-19 severity in people younger than 42 who have received the MMR II vaccine.
“This is in addition to other associations showing that the MMR vaccine can protect against Covid-19. It may also explain why children have a much lower rate of Covid-19 cases than adults, as well as a much lower death rate. minor, “said the study author. Jeffrey E. Gold from the University of Georgia in the USA.
“Most children receive their first MMR vaccine around 12 to 15 months of age and a second between 4 and 6 years of age,” Gold added.
In the new study, the researchers divided 80 participants into 2 groups. The MMR II group consisted of 50 US-born participants who would primarily have MMR antibodies to the MMR II vaccine.
A comparison group of 30 participants had no MMR II vaccination record and mainly had MMR antibodies from other sources, including previous measles, mumps, and / or rubella illnesses.
The researchers found a significant inverse correlation between mumps titers and Covid-19 severity within the MMR II group.
There were no significant correlations between mumps titers and disease severity in the comparison group, between mumps titers and age in the MMR II group, or between severity and measles or rubella titers in any group .
This is the first immunological study to evaluate the relationship between the MMR II vaccine and COVID-19.
The statistically significant inverse correlation between mumps titers and Cpvod-19 indicates that there is an involved relationship that warrants further investigation, “said study co-author David J. Hurley.
The MMR II vaccine is considered a safe vaccine with very few side effects.
“If it has the ultimate benefit of preventing Covid-19 infection, preventing the spread of Covid-19, reducing its severity, or a combination of any or all, it is a very high-reward, low-risk intervention.” the authors.
