Government research in the UK shows that two Covid-19 vaccine responses are needed to effectively protect against infectious diseases from the coronavirus species that were first identified in India, according to two people who reported earlier.
Two vaccines protect 81% against B. 1.617.2 strains found in India, and 87% against B.1.1.7 strains that were first identified in Kent in southeastern England, according to Public Health England. at a meeting of the New Emerging Respiratory Virus Threats Advisory Group (Nervtag).
Two participants at a Nervtag meeting on Friday said the site showed that one level provides 33% protection against symptomatic infections from B. 1.617.2, and 51% against B.1.1.7.
This shows a single shot provides a 35% lower protection against B. 1.617.2 compared to B.1.1.7, according to a Financial Times review.
PHE statistics include everything from BioNTech / Pfizer and Oxford / AstraZeneca jabs.
The rapid spread of B. 1.617.2 in the pockets of England has cast doubt on the road map in the country due to the deviation, the next phase is due to take place on June 21st.
PHE said: “Public Health England scientists are evaluating the status of the vaccine against B. 1.617.2 type Sars-Cov-2. We will make the results of this review now.”
New PHE studies should confirm the need to take two doses of Covid-19 vaccine to protect against B. 1.617.2.
Last week the government reduced the gap between people over the age of 50 from 12 to eight weeks, to ensure that those at risk in the UK received the vaccine as quickly as possible. It also introduced more vaccines in B. 1.617.2 tropical areas such as Bolton and Blackburn and Darwen.
Two vaccines presented at the Nervtag conference on Friday by Neil Ferguson, a well-known infectious disease specialist from Imperial College London, supported the new PHE study, with one claiming that only once vaccinated was about 50% against B. 1.617.2 compared to B .1.1.7, and the other shows a 20% reduction.
The rate of energy depletion is comparable to the comparison of the B.1.351 type that was first detected in South Africa, while one BioNTech / Pfizer vaccine has been found to protect only 17% of Covid-19-confirmed infections, rising to 75% after on two scales.
Scientists in the UK have been rushing to determine the amount of B. 1.617.2 more than other available species, most notably B.1.1.7.
The films released last week by government advisers are said to be about 50% more contagious than B.1.1.7, although new information last week means it may not be that big.
Most government publications released Friday from Bolton have defended immunity to vaccines, while Covid-19 cases drop significantly among seniors who were selected as jabs than seniors.
Coronavirus has risen slightly in the UK last week, according to the Office for National Statistics
