Sinovac's COVID-19 vaccine induces quick immune response: study

[TexasTowelie]

SINGAPORE/BEIJING (Reuters) - Sinovac Biotech’s experimental COVID-19 vaccine CoronaVac triggered a quick immune response but the level of antibodies produced was lower than in people who had recovered from the disease, preliminary trial results showed on Wednesday.

While the early to mid-stage trials were not designed to assess the efficacy of CoronaVac, researchers said it could provide sufficient protection, based on their experience with other vaccines and data from preclinical studies with macaques.

The study comes hot on the heels of upbeat news this month from U.S. drugmakers Pfizer and Moderna as well as Russia that showed their experimental vaccines were over 90% effective based on interim data from large, late-stage trials.

CoronaVac and four other experimental vaccines developed in China are currently undergoing late-stage trials to determine their effectiveness in preventing COVID-19.

1. I wonder if you'd see similar disparities

between people who'd gotten any disease naturally (small pox, measles, mumps, and so on) compared to those who got a vaccine?

2. I am wondering if the Pfizer and Moderna vaccines can be mixed.

First dose of one and second of the other scenario.

If they can, then supplies can be utilized more efficiently.

3. I like your thinking

Doubtful the companies would agree to collaborate like that, but it seems like a sound idea.
