Data from all over the world is making it clear that the Chinese vaccines are far less effective. The director of the Chinese Center for Disease Control and Prevention even admitted this, and it probably why the Chinese have done deals to get Western vaccines.
To be fair though, it does appear that any vaccine is better than no vaccine in reducing severe illness and death. So while countries might have good reason not to let tourists who have been vaxxed with Chinese shit into their countries without testing, itâs not all bad news for the countries where the vaxxed people live.
The mRNA vaccines are proving to be very effective. You mentioned Israel. Hereâs data from the US, where Pfizer and Moderna are the most widely used.
101 million fully vaxxed people as of April 30, 2021 and:
A total of 10,262 SARS-CoV-2 vaccine breakthrough infections had been reported from 46 U.S. states and territories as of April 30, 2021. Among these cases, 6,446 (63%) occurred in females, and the median patient age was 58 years (interquartile range = 40â74 years). Based on preliminary data, 2,725 (27%) vaccine breakthrough infections were asymptomatic, 995 (10%) patients were known to be hospitalized, and 160 (2%) patients died. Among the 995 hospitalized patients, 289 (29%) were asymptomatic or hospitalized for a reason unrelated to COVID-19. The median age of patients who died was 82 years (interquartile range = 71â89 years); 28 (18%) decedents were asymptomatic or died from a cause unrelated to COVID-19. Sequence data were available from 555 (5%) reported cases, 356 (64%) of which were identified as SARS-CoV-2 variants of concern,§ including B.1.1.7 (199; 56%), B.1.429 (88; 25%), B.1.427 (28; 8%), P.1 (28; 8%), and B.1.351 (13; 4%).
Only 10,000 odd breakthrough infections in 101 million people.
Of course not all breakthrough infections will be detected because many/most people wonât have symptoms. But thereâs no doubt that the Pfizer/Moderna vaccines are stunningly effective, especially in younger people.
Iâd surmise that the breakthrough infections are more likely occurring in people who are older and have health issues that prevent their immune systems from mounting a stronger response to the vaccines. In time itâs possible theyâll be able to identify these people and find ways to help them.
