Covid the vaccine: some good news




Discussing the various vaccines being developed for covid: The US and EU and UK vaccines seem to be working well in the phase three trials.

so might be released in October for the US and in Europe.

The Russian and Chinese vaccine will be used without phase three vaccines (translation: They will use them without full screening if they work or have side effects because it is urgent to get something to use, and because the phase II studies look good).

No recent news if the Philippines will be able to get a vaccine to use, except older news articles suggest the Philippines will be used for the phase III of the Russian vaccine (but since the Philippines was harmed by the Dengue vaccine problems, it is a problem since the government officials and politicians might stop it's use)

Remember: Both Brazil and India have pharmacutial companies who are able to produce vaccines if given the instructions.

When you read "ain't it awful" stuff about the vaccines, I agree with the good doctor: None of the anti vaxers have seen the diseases that are prevented by vaccines. I have seen some of them both in the USA (I predate measles vaccine) and in Africa. So their paranoia will kill people: but probably not the anti vaxers here, because usually healthy people who aren't too old don't get die with Covid, 

except for health care workers... the reason? How sick you get depends on the dosage you are in contact with. Two of our relatives in the UK who work in respiratory therapy (nurse anesthetists) got it, one a mild case and one was very sick but recovered. But that explains why the death rate of health care workers is so high.


a lot of the lecture is technical: about different approaches to the vaccine,  the description gets a bit technical.

One problem is the US vaccine might need two injections to get an adequate antibody level. 

Antibodies help, but the real test is if the vaccines enable the T cell lymphocytes to work for cellular immunity. 

What I did find interesting was that the different vaccines are using different approaches: one is based on adenovirus vaccine, and another uses an RNA appraoch. Not in the lecture is that the Russian vaccine uses an approach similar to the Ebola vaccine.

Dr. C points out the really good news is that Covid has not killed a lot of people )(One to four percent of all infected patients  i.e. the level of severe influenza) but essentially is not very very bad (as in bird Influenza or SARS or MERS or Ebola, which kill  one third to over half of those infected).

this epidemic has done two things: 

One: Notified countries they need to be prepared for the next epidemic, (not just keep supplies for PPE available, because hey, most hospitals etc had stockpiles of PPE, but they didn't have the HUGE amounts that were needed).

Second: maybe countries won't try to coverup outbreaks: e.g. so the one month delay by China to notify the world won't happen again, and there will be less negative feedback when folks shut down border (as look at the racism attacks when Trumpieboy shut down flights from China, although that fact is constantly denied i.e. gas-lighted by the MSM).

And three: the basic science in developing this vaccine will enable other vaccines to be produced for a new disease more quickly.
