巴西政府:多亏买了中国疫苗!两种变异病毒都能抵抗;实验表明:辉瑞疫苗对南非变异病毒免疫效果降低2/3

我没有立场,只想追求真相与正义。我没有主张,只是要驳斥胡说八道。

灭活疫苗是抗原表位全谱疫苗,mRNA疫苗只有突刺S蛋白位点。如果S蛋白变异足够大,美国的疫苗失效,打了也是白打。

不是说mRNA疫苗修改对付变异只要6周吗?现在开始吧,别耽误啊。

唉!以色列最惨。

SERRANA, Brazil (Reuters) -

The COVID-19 vaccine developed by China’s Sinovac Biotech is effective against the UK and South African variants, the vaccine's Brazilian partner said on Wednesday, citing test results in Chinese trials.

"We have tested this vaccine in China against the English and the South African variants, with good results," said Dimas Covas, head of the Butantan biomedical center in Sao Paulo which lead domestic trials of the Chinese vaccine and is supplying doses to Brazil's Health Ministry.

Covas did not give any more details on exactly how effective the vaccine proved against these strains.

Butantan is also testing the vaccine, known as CoronaVac, against the Brazilian variant of the virus which appeared in the city of Manaus, he said.

"Soon we will have the results and we are very positive it will do the job," Covas said.

Covas was speaking at a news conference in the small city of Serrana, in the interior of Sao Paulo state, where Butantan began on Wednesday a mass vaccination campaign aimed at inoculating the entire adult population against COVID-19 to test whether it lowers the infection rate.

Covas said he expects CoronaVac to have an advantage over other vaccines due to the technology it uses - an inactivated version of a coronavirus strain.

The efficacy of the Chinese vaccine against the Brazilian strain in particular will be vital to Brazil. The government has secured 100 million doses and made the vaccine a centerpiece of its inoculation campaign.

Covas' comments come as several cities in Brazil, including state capitals of Rio, Salvador and Cuiaba have suspended new vaccinations as they ran out of doses.

你可真是可爱 以色列和我们用的是一样的疫苗吧


你也不要太悲观。
只是说效果下降了3分之2,还有3分之一效果,不是完全无用。

唉,咱们怎么办呢,估计以后还有各种变异,每年政府都要跟感冒疫苗一样,但是要花大钱不停买covid-19疫苗,估计又要加税了。 制造疫苗的公司走运了,可以买股票。

With more than 2.5 million doses administered, Chile is moving fast on COVID-19 vaccination drive
Chile is streaking ahead of the rest of Latin America in its campaign to vaccinate its population against the coronavirus, which the Andean country’s leaders hope can help not only beat back the virus but also unite the nation.

As of Feb. 18, the copper-producing country had given over 2.5 million doses of vaccine, enough for around one shot for 12 in every hundred people, according to Our World in Data. It could fully vaccinate 10% of its population with two doses per person in just over 20 days at its current rate, Reuters data show.

That puts it in the top 10 globally of larger countries and compares to 172 days for Brazil and over 1,000 days for Mexico, which has faced delays in its inoculation program.

With the arrival of Sinovac doses, it set up 1,400 mobile clinics around the country at the start of February and by last Thursday had given some 2.57 million vaccinations.
