In India’s eradication of smallpox and polio, lessons on how to (and how not to) tackle Covid-19 vaccination - The Indian Express In India’s eradication of smallpox and polio, lessons on how to (and how not to) tackle Covid-19 vaccination - The Indian Express Posted: 12 May 2021 12:00 AM PDT On June 14, 1802, Anna Dusthall, a three-year-old girl of a mixed racial parentage in Bombay, was given a dose of cowpox vaccine that the Scottish doctor Helenus Scott had received from Basra in the Middle East. Scott had injected the vaccine in about a dozen or so children, and Dusthall was the only one who took the infection. A little over a week later, he observed a vaccine vesicle on her arm, the lymph from which was used to inoculate other children, five of them being in Bombay. Very little is known about Dusthall, except that her "quietness and patience in suffering the operation" had ushered a new epoch in the history of medicine in the s...

Can We Stop COVID-19 Like We Stopped Polio? - Healthline Can We Stop COVID-19 Like We Stopped Polio? - Healthline Posted: 03 May 2021 12:00 AM PDT Share on Pinterest The speed of vaccinations has slowed in recent weeks. Spencer Platt/Getty Images Experts believe it will take vaccinating 70 to 90 percent of Americans before we reach herd immunity. Currently nearly 1 in 4 people are against getting any of the vaccines, according to a recent NPR/Marist poll. Experts point out that the push for COVID-19 vaccines face challenges that immunization campaigns have not. As of May 3, more than 147 million Americans have received at least one dose of the available COVID-19 vaccines. That's more than 44 percent of the population. But experts estimate we won't hit herd immunity — when enough people are vaccinated to essentially stop the transmission of the virus — until 70 to 90 percent of people are vaccinated. Currently, near...

Why even with vaccines, COVID-19 will always be with us - The Detroit News Why even with vaccines, COVID-19 will always be with us - The Detroit News Posted: 10 May 2021 12:00 AM PDT Jason Gale, Bloomberg Published 4:31 p.m. ET May 10, 2021 | Updated 4:43 p.m. ET May 10, 2021 The road to eliminating COVID-19 is long and paved with uncertainty. Many countries are counting on vaccines to build sufficient immunity in their populations so that SARS-CoV-2 isn't able to find susceptible people to infect, causing transmission of the coronavirus to slow and eventually stop. But even with the rollout of highly effective vaccines, immunization coverage may not reach that level -- the so-called herd immunity threshold -- anytime soon. For one thing, it's not known what level of immunity is required. There's also the threat of emerging coronavirus variants that may weaken the effectiveness of immunizations. 1. Can COVID-19 be eradic...

We can get a COVID-19 vaccine in months but not one for HIV? - Escanaba Daily Press We can get a COVID-19 vaccine in months but not one for HIV? - Escanaba Daily Press Posted: 22 May 2021 12:04 AM PDT Metro photo Vaccines to protect against COVID-19 were create and implemented at speeds unheard of prior to the pandemic. So why, after 37 years, isn't there a vaccine for HIV? The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts. Today's piece is by Ronald C. Desrosiers, of the University of Miami. (THE CONVERSATION) — Smallpox has been eradicated from the face of the Earth following a highly effective, worldwide vaccination campaign. Paralytic poliomyelitis is no longer a problem in the U.S. because of development and use of effective vaccines against the poliovirus. In current times, millions of lives have been saved because of rapid deployment of effective vaccines again...
