When a COVID cluster contains persons who have been vaccinated against the virus, we often hear grumblings from those who question the value of immunization.
However, go below the headlines. You will generally find the answer: most people vaccinated and caught COVID-19 did not die, did not have severe symptoms, and did not require hospitalization.
The risk of dying from COVID for unvaccinated Australians in their older years is considerable. Around 32% of unvaccinated persons in their 80s who develop COVID will die from it. It’s approximately 14% for those in their seventies. (It reduces to about 3% for unvaccinated persons in their 60s.) And it’s less than 1% for those under 50.) The good news is that both Pfizer and AstraZeneca’s COVID-19 vaccines, even the more virulent Delta variant, are highly successful at preventing severe illness and death from COVID-19. So, how well do our vaccinations work? According to preliminary statistics from the United Kingdom, after receiving your first dosage of Pfizer or AstraZeneca, you’re 33 percent less likely to develop the Delta version than an uninfected individual.
This climbs to 60% for AstraZeneca and 88 percent for Pfizer two weeks following your second dosage. This information applies to all types of COVID-19, from moderate to severe. However, when it comes to reducing your chance of having a painful disease that needs hospitalization, vaccination coverage is high for both. The vaccinations developed by Pfizer and AstraZeneca are 96 percent and 92 percent effective in reducing Delta variant hospitalizations, respectively.
Why do some people acquire COVID despite having been vaccinated? Vaccines are not impenetrable barriers. They do not kill the virus or disease they are attempting to eradicate. Vaccines, on the other hand, encourage the immune system to produce antibodies.
