Two doses of Pfizer-BioNTech vaccine 'highly effective against Covid disease, illness and death'
06 May, 2021
Two doses of Pfizer-BioNTech's Covid-19 vaccine provide a lot more than 95 % protection against infection, hospital admission, severe illness and loss of life, including among older people.
This is the findings of the initially national-level evaluation of the vaccine's performance in Israel, published found in The Lancet.
The analysis, predicated on national data, also reveals the general public health benefits associated with a countrywide vaccination programme, found to be the key cause of a decline in Covid-19 infections in Israel.
While the findings are encouraging, the authors stress that challenges to controlling the pandemic continue to be.
The time of immunity to Covid-19, due to infection and immunisation, remains unidentified, in fact it is possible that vaccine-resistant variants could emerge.
And attaining herd immunity will demand a continued rise of vaccination coverage worldwide.
“As the country with the highest proportion of its people vaccinated against Covid-19, Israel offers a unique real-world chance to determine the potency of the vaccine and also to observe wider ramifications of the vaccination program on public health,” explained lead author Dr Sharon Alroy-Preis, of the Israeli Ministry of Health.
“Until this point, no country on the globe had described the national open public health impact of a good nationwide Covid-19 vaccination campaign.
“These insights are hugely crucial because, while you may still find some extensive challenges to overcome, they provide true hope that Covid-19 vaccination will eventually permit us to regulate the pandemic.”
The analysis said the Pfizer-BioNTech vaccine was impressive against Covid-19 for all persons older than 16 years.
It provided 95.3 % protection against an infection and 96.7 % against death seven days after the second dose.
Safety against symptomatic and asymptomatic an infection was 97.0 % and 91.5 %.
The vaccine can be highly effective for preventing the need for hospital treatment and extreme illness, at 97.2 per cent and 97.5 %.
By 2 weeks after vaccination, security from a second dose increased to 96.5 % against infection, 98 % against the necessity for medical therapy and 98.1 per cent against death.
Protection among older people were as strong seeing that those for younger people.
The analysis indicated that people over 85 years had 94.1 per cent protection against infection, 96.9 % against the need for hospital treatment and 97 % against death, a week following the second dose.
Persons aged 16 to 44 years had 96.1 % protection against infection, 98.1 % against the need for medical therapy and 100 % against death.
