The new bivalent booster vaccines for Covid are available now, but the path to making these ready for adults earlier this month wasn't easy.

新 Covid 双加强疫苗现已上市，但在本月早些时候为成年人准备这些疫苗并不容易。

In the early 2000s, vaccines known as bivalent oral vaccines were developed to target only PV1 and PV3 because of the drop in circulation of the PV2 strain.

在 21 世纪初，由于 PV2 毒株传播减少，开发了仅针对 PV1 和 PV3 口服疫苗。

This is because the federal government has purchased nearly two billion doses of COVID vaccines and 171 million bivalent boosters—the ones formulated to cover Omicron strains.

这是因为联邦政府已经购买了近 20 亿剂 COVID 疫苗和 1.71 亿剂加强剂——这些疫苗是为覆盖 Omicron 毒株而配制。

政府， 他们不得不从不同项目中借钱、乞讨和窃取资金， 才能真正从辉瑞和 Moderna 购买新助推器。

The new bivalent booster protects you against both the original SARS-CoV-2 strain and Omicron's BA. 4 and BA. 5 subvariants, and it's likely to provide some protection against the newer variants too.

新加强针能防护新冠原始毒株和奥克戎 BQ. 4 和 BQ. 5 亚变异株，而对于更新变异，它也可能提供某些防护。

The autumn Covid-19 booster shots we have just been offered are one such example – these bivalent vaccines target the original strain of Sars-CoV-2 (the virus that causes Covid-19) alongside the Omicron variant.

我们刚刚获得秋季新冠加强疫苗就是这样一个例子——这些双疫苗针对是 Sars-CoV-2 原始毒株（导致新冠病毒）和奥克戎变种。

So right now, if you're asking a clear question, of today, with the bivalent BA.4-5 boosters or updated vaccines is a better terminology to use, they are available now throughout the country.

Just 15% of people in the U.S. ages 5 and older have gotten a bivalent booster, according to the CDC, which means many people are currently not as protected as they could be against the new variant.
