Public Health: COVID-19 Vaccine protection lasts for least 6 months ─Researchers

Researchers who have analysed various COVID-19 studies discovered that while COVID-19 Vaccines lose some effectiveness in preventing SARS-CoV-2 infection, the vaccines retain nearly all of their ability to prevent severe disease up to six months after full vaccination.

The study, published in The Lancet online was a joint effort by researchers at the Johns Hopkins Bloomberg School of Public Health and the World Health Organisation (WHO), report said.

The work examined research conducted before the emergence of the Omicron variant of the Coronavirus pandemic late 2021.

Melissa Higdon, Co-first author of the study, said: “There is an indication here of waning vaccine effectiveness over time, though it is encouraging that protection from severe disease, the most worrisome outcome, seems to hold up well.”

Children have better innate immunity against Coronavirus than adults

In a related study, researchers have opined that since the start of the pandemic, children infected with the COVID-19 virus have generally fared better than adults who get the disease. But, medical doctors have not known why.

However, in a fresh study, Yale University scientists found that children are better at managing the first line of defence known as the innate immune system than adults.

That’s not to say that some children don’t get very sick and even die from the virus, but most of them have very mild symptoms if they have symptoms at all.

Scientists say innate immunity serves to coordinate the first response when a patient is infected with the virus.

It is different than adaptive immunity, which develops more slowly and usually targets a specific disease or ailment, experts said.
