The latest on COVID 19
CURRENT Covid 19 Situation
Patients are still hospitalised and people are dying still of Covid related problems, much less so in the UK now.
As of this date 34 million British people have received their first free anti-C19 vaccination. The UK is leading the world in this strategy to overcome this pandemic.
We should be so very grateful to our Government….what a truly amazing feat.
We are not quite completed, but by end of July 2021, it is predicted 80% of UK adults will have had at least one vaccine.
So what do the experts say about Herd Immunity:-
Herd immunity (aka community immunity) occurs when enough people in a population are immune to a disease, making person-to-person transmission less likely. The infection, in effect, no longer has the upper hand.
Vaccines, by contrast, work by training the immune system to create antibodies so that when you encounter the disease, your body will quickly mount a defense. The more people who are vaccinated, the less opportunity the virus has to replicate and spread. At some point, the community—or “herd” —is protected, even people who aren’t immune or cannot be vaccinated, such as newborn babies, says the CDC.
Depending on how contagious an infection is, the Johns Hopkins Bloomberg School of Public Health says 50% to 90% of a population must be immune before herd immunity is achieved. Herd immunity against measles, for example, requires about 95% of the population to be inoculated; for protection from polio, it’s about 80%, according to the World Health Organization (WHO).
Since COVID-19 is caused by a new virus, the percentage of the population that must be vaccinated to achieve herd immunity is unknown. WHO says a “substantial” proportion of the population would need to get their shots. Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases and a Biden administration adviser, has been revising estimates upwards from 60% to 70% in the pandemic’s early days to close to 90% more recently, the New York Times reports.
