“There’s no such thing as a perfect vaccine?.?.?.?with Covid it’s no different,” said Professor William Schaffner, an infectious disease specialist at Vanderbilt University. The yellow fever jab, for example, is widely understood to be the most effective live-virus vaccine ever invented, with a single dose generating long-lasting immunity in 98 per cent of those vaccinated. But even that means that on average 2 per cent of people will still get infected.
Phase 3 trials for most of the leading Covid-19 jabs showed an efficacy against symptomatic infection of more than 90 per cent. Real-world studies of effectiveness in the UK, Israel and Canada suggest that vaccines are displaying a slightly lower effectiveness outside of the trial environment, probably because of the spread of the more vaccine-resistant Delta variant. Estimates put protection against symptomatic infection, depending on the vaccine, at between 60-90 per cent. According to Public Health England, about 17 per cent of the 105,598 Delta variant cases reported across England in the four weeks to July 19 were among fully vaccinated people. PHE counts people as fully vaccinated 14 days after their second dose.
Anthony Masters, a member of the UK’s Royal Statistical Society, said fully vaccinated people were likely to make up a “bigger proportion” of cases as vaccine coverage was extended, particularly in younger groups who face a higher exposure risk because of greater social mixing. “If you get extremely high coverage across the different ages, it’s plausible that cases could become majority among fully vaccinated people,” he said. About 55 per cent of the UK population had received both doses by July 21. In Israel, where nearly 60 per cent of the population are fully vaccinated and coverage is spread more evenly across age cohorts, 52 per cent of about 6,000 people who tested positive in the week to July 21 were fully vaccinated. Are some fully vaccinated people at more risk of falling ill than others? Very few fully vaccinated people who test positive for Covid-19 are getting seriously ill. According to PHE’s real-world studies, the BioNTech/Pfizer vaccine is still 96 per cent effective against hospital admission, while the Oxford/AstraZeneca shot is 92 per cent effective. But Natalie Dean, a biostatistics professor at Emory University in Atlanta, stressed that these figures were averages and that efficacy depended on people’s existing risk profiles. “Everything is relative when it comes to vaccines and risk,” she said. A Financial Times analysis of global infection fatality rates, for example, suggests that a double-jabbed 80-year-old person now faces about the same mortality risk as an unvaccinated 50-year-old.”
Vaccine: A preparation that is used to stimulate the body's immune response against diseases. Vaccines are usually administered through needle injections, but some can be administered by mouth or sprayed into the nose.
This is exactly what the Covid vaccine does, it boosts immunity against the covid virus-producing anti-bodies that can and do reduce the serious effect the virus can produce in those unvaccinated.
Some ignorant people cite Israel as an example of the vaccine failing due to the high number of people tested as having covid and also vaccinated, but logically if the majority of the population are vaccinated then of course those tested positive will be vaccinated.
About two-thirds of people who die on UK roads are wearing a seatbelt, but this is a consequence of usage rates of nearly 99 per cent, so using the Non-vaccine logic this means wearing a seat belt causes death.
