The first dose of COVID-19 vaccines reduces coronavirus transmission by around two-thirds, says British Health Minister Matt Hancock. As he reported, this is indicated by preliminary data.
Whether or not vaccinated people can transmit the coronavirus without getting sick themselves remains a key unknown. If they can transmit it means everyone must be vaccinated for full protection. However, if the vaccine also stops the spread of the virus, then it would have a much greater impact on the pandemic, as each person who is indirectly vaccinated will also protect other people, said the minister.
Hancock mentioned the reduction of carry-over in an interview on Sky News when asked about the possibility of vaccinating children in the future.
Vaccinating children is important in trying to stop the spread of the disease, and we have early evidence of the effect of vaccination in stopping transmission. The first dose appears to reduce disease transmission by about two-thirds, but we need more evidence for that, said the UK Health Minister.
The two-thirds figure he cited had previously appeared in a preliminary study on AstraZeneca’s effects on viral transmission, published in early February in The Lancet, but only one of the two vaccines currently in use in the UK.
As part of the lockdown recovery plan announced by Boris Johnson on Monday, government agency Public Health England is expected to provide more complete data on the impact of vaccines on virus transmission.
Hancock also said vaccinations have resulted in COVID-19 hospital admissions now falling faster than it was during the declining wave of the first wave of the epidemic. This week, the number of patients in hospitals fell below the peak in the first wave for the first time since December. On Friday, there were less than 18,000 in hospitals. patients with COVID-19, by almost 3,000 less than the peak of the first wave.
