A friend seeking my opinion had sent to me an anonymous post which I rather suspect is “making the rounds” on social media, which most likely is FaceBook. The following is my reply.

This young girl in Bangladesh was infected with smallpox in 1973. Freedom from smallpox was declared in Bangladesh in December, 1977 when a WHO International Commission officially certified that smallpox had been eradicated from that country.
Is it a vaccine💉? It took 25 years for a chicken pox vaccine to be developed. [It seems as if the writer is beginning to understand the complexity and magnitude of the problem of vaccine development. The first varicella zoster vaccine was tested in Japan in 1974, and approved by the Japanese government in 1986 – a span of 12 years. The FDA approved a varicella vaccine in 1995, and in 1996 the CDC’s Advisory Committee on Immunization Practices (ACIP) voted to formally approve the vaccine for widespread use.] The smallpox inoculation was discovered in 1776 [Dr. Edward Jenner, MD, developed the first smallpox vaccine (using cowpox) in 1796.] and the last known natural case was in 1977. [SEE EXTENDED COMMENTS FOLLOWING THIS PARAGRAPH] We have a flu vaccine that is only 40 to 60% effective (that’s generous- the last two years it was more like 20-25%) [Influenza vaccines are developed in advance of the annual “flu season” using statistical inferences (prediction), and from 2004/2005 to 2018/2019 vaccine effectiveness (VE) estimates have ranged on average from 10% to 60%. For the 2018/2019 season, the overall VE rate was 29%.], less than half of the US population chooses to get one [The remark presumes that all people would get an influenza vaccine if they could – however, many cannot, typically either for reasons of lack of access, availability, or cost. In the Armed Services, vaccines are mandatory. The Centers for Disease Control and Prevention (CDC) analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS) to estimate flu vaccination coverage for the U.S. population of adults aged ≥18 years during the 2017–18 flu season. Flu vaccination coverage among adults was 37.1%, a decrease of 6.2 percentage points from the previous flu season.], and roughly 20,000 Americans still die annually due to flu or flu complications. [From 2010/2011 through 2018/2019 influenza-related deaths have ranged from 12,000 to 61,000. The 2017/2018 year saw 61,000 influenza-related deaths, while the 2018/2019 year saw 34,157.] [EXTENDED COMMENTS: In late 1975, Rahima Banu, a three-year-old girl from Bangladesh, was the last person in the world to have naturally acquired variola major and the last person in Asia to have active smallpox.
