Until now, the Pfizer and Moderna vaccines have targeted the virus's original strain.

到目前为止，辉瑞和莫德纳疫苗都是针对病毒的原始毒株。

Research from China suggests that the Delta variant copies itself much faster and makes 1,000 times more virus in the body compared to the original strain.

中国研究表明，与原始病毒株相比，" 德尔塔" 变种复制自身的速度要快得多，在体内产生的病毒要多出1000倍。

Delta is known to be much more transmissible than previous strains and appears to produce about 1,000 times as much virus in the body as the original strain.

众所周知，Delta 比以前的毒株更容易传播，并且在体内产生的病毒数量似乎是原始毒株的 1,000 倍左右。

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.

新的二价加强针能防护新冠原始毒株和奥密克戎 BQ. 4 和 BQ. 5 的亚变异株，而对于更新的变异，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.

我们刚刚获得的秋季新冠加强疫苗就是这样一个例子——这些双价疫苗针对的是 Sars-CoV-2 的原始毒株（导致新冠的病毒）和奥密克戎变种。
