Chile administered nearly 9 million doses of the Sinovac vaccines in February, with an average of 47 doses per 100 people, making it the country with the highest vaccination rate in South America. However, the number of positive test results recorded in Chile rose instead of fell, and a new high of 7,626 cases was recorded in a single day on March 26, leading to a tight supply of hospital beds and a recent lockdown of the capital city of Santiago.
Here's another...
Turkey started to administer Sinovac vaccines in mid-January and at least eight million people have been injected with the vaccine, accounting for more than 10 percent of the population. But their case numbers also rebounded in late February, with 37,303 new cases recorded on March 30, the highest single-day figure since the outbreak on March 11 last year.
In addition, Pakistan, which has been using the Chinese vaccine since early February, is now experiencing a third wave of the pandemic, with the national positivity ratio rising to 11 percent, the highest level since the outbreak. More than 20 cities have been “closed” due to the severity of the outbreak.
Pakistani President Arif Alvi wrote on March 29 that he tested positive after receiving the first dose of a vaccine produced by the Chinese National Pharmaceutical Group Corp on March 15. Prior to that, Pakistani Prime Minister Imran Khan also tested positive for the virus on March 18, two days after receiving his first dose of the vaccine manufactured by the same Chinese company.
Can anybody give a logical/scientific explanation to what's happening here? Aren't vaccines supposed to eventually DECREASE the number of cases as the population approaches herd immunity with the increases in vaccination?
