There are early signs that vaccinated people could transmit the coronavirus delta strain as easily as unvaccinated people, according to the Public Health Agency of England (PHI).
The findings coincide with what they said from the US Centers for Disease Control and Prevention (CDC) last week, where they warned that vaccinated people infected with the delta variety, unlike other strains, could
The highly contagious delta strain of coronavirus is globally dominant and maintains a pandemic that has killed more than 4.4 million people, including more than 130,000 in the UK.
Vaccines have been shown to provide good protection against serious illness and death after delta infection, especially two doses, but there is less evidence that vaccinated people can still transmit the virus to others.
"Some initial findings suggest that the level of virus in the infected virus DELTA vaccinated may be similar to those found in unvaccinated people," BRITISH PHO, adding:
“There can be consequences for infecting people, whether they are vaccinated or not. “But this is an early analysis of the research and further focused studies are needed to confirm whether this is the case.”
The PHI reported that as of June 19, 55.1 per cent of hospitalized people infected with delta had been unvaccinated and 34.9 per cent had received both doses of the covid-19 vaccine.
Nearly 75 per cent of the British population has received both doses, and PHE states that “as more people are vaccinated, a higher relative proportion of those vaccinated in the hospital will be seen”.
PHE also states that another species, known as B.1.621, discovered in Colombia, shows signs of evading an immune response from vaccines or a previous infection.
The PHI stated that the virus was “under investigation”, but did not declare it a “worrying species” – a sign that could provoke a strong political reaction.
"There are preliminary laboratory evidence suggesting that vaccination previous infections may be less effective in preventing infection B.1.621", PHI said, adding that 37 cases of virus have been confirmed in England.
“However, these data are very limited and further research is needed. “There is no evidence to suggest that more than the dominant delta species is being transmitted,” the agency said.
