Who knows. Maybe their shots are made out of bats and pangolin scales although according to Wikipedia they have "significantly decreased immune responses". So that might account for the poor efficacy results of the Chinese vaccine.
This is interesting.
"People who recover from coronavirus have a similar level of protection against future infection as those who receive a Covid vaccine – at least for the first five months, research suggests."
"A Public Health England (PHE) study of more than 20,000 healthcare workers found that immunity acquired from an earlier Covid infection provided 83% protection against reinfection for at least 20 weeks."
“The immunity gives you a similar effect to the Pfizer vaccine and a much better effect than the AstraZeneca vaccine and that is reassuring for people. But we still see people who could transmit and so we want to strike a note of caution,” Prof Hopkins said. In clinical trials, two doses of the Pfizer vaccine had an efficacy of 95%, compared with 62% from two doses of the Oxford/AstraZeneca vaccine.

I was listening to the Science Weekly podcast which this week went to the UK government laboratories where positive COVID-19 tests are followed up by tests of that infected material against vaccines as well as other activities. It sounds very encouraging as far as the latest strains go when tested against the vaccines being made available in the UK and Europe.
