Get the bad news out of the way first – https://www.independent.co.uk/news/health/coronavirus-reinfected-hong-kong-covid-19-study-a9685571.html

“Researchers at Hong Kong University’s department of microbiology said genetic sequencing of the virus showed that a Hong Kong man was infected twice by different versions of the coronavirus months apart.

According to the study, the patient was a 33-year-old man who was in good health. When he was first infected, he suffered a cough, sore throat, fever and headache for three days. He had a test that confirmed Covid-19 and he was hospitalised on 29 March. He was discharged on 14 April after two negative swab tests.

Four months later, he was returning to Hong Kong from Spain via the UK when he tested positive during entry screening at Hong Kong airport on 15 August. He was hospitalised again but had no symptoms throughout.”

“Our findings suggest that Sars-CoV-2 may persist in the global human population as is the case for other common-cold associated human coronaviruses, even if patients have acquired immunity via natural infection. “Since the immunity can be short-lasting after natural infection, vaccination should also be considered for those with one episode of infection.“Patients with previous Covid-19 infection should also comply with epidemiological control measures such as universal masking and social distancing.” ”

The silver lining is the second time he didn’t have any symptoms but was a carrier.

It would seem China is also far into the vaccine development. This should not be a surprise given authoritarian govt are more efficient at implementation and they probably had more data on covid than anyone initially. https://www.cnn.com/2020/08/24/asia/china-vaccine-doctors-workers-intl/index.html

“China has been using an experimental coronavirus vaccine on people who work in "high risk" professions since July, including front line medical professionals and border inspectors, a senior official from the national health commission revealed over the weekend.”

“This isn’t the first time the country has approved the use of an experimental vaccine. In June, the Chinese government approved the use of a different vaccine candidate for the country’s military.

That vaccine — which was jointly developed by the Beijing Institute of Biotechnology, part of the Chinese government’s Academy of Military Medical Sciences, and vaccine company CanSino Biologics — was given "military specially-needed drug approval" by China’s central military commission in June. The special permission lasts for one year and will only apply to military personnel. China is the world’s largest producer and consumer of vaccines, and can supply more than 1 billion doses of a vaccine annually from 40 manufacturers across the country, according to the China Human Vaccine Industry Report 2018-2022.

China currently has more coronavirus vaccine candidates in human trials than any other nation.”
