Covid-19 𝐖𝐡𝐲 𝐝𝐨 𝐈 𝐧𝐞𝐞𝐝 𝐭𝐨 𝐭𝐚𝐤𝐞 𝐭𝐡𝐞 𝐛𝐨𝐨𝐬𝐭𝐞𝐫, 𝐨𝐫 𝐭𝐡𝐞 𝐭𝐡𝐢𝐫𝐝 𝐬𝐡𝐨𝐭 or the second booster?

Many have asked me questions about #boosters. So here are top 4 questions about the importance of boosters and who should take them.

很多人最近问我关于追加剂的一些问题。想要借此和大家分享关于追加剂的四大常见问题。

1️⃣ 𝐖𝐡𝐲 𝐝𝐨 𝐈 𝐧𝐞𝐞𝐝 𝐭𝐨 𝐭𝐚𝐤𝐞 𝐭𝐡𝐞 𝐛𝐨𝐨𝐬𝐭𝐞𝐫, 𝐨𝐫 𝐭𝐡𝐞 𝐭𝐡𝐢𝐫𝐝 𝐬𝐡𝐨𝐭?

A booster, or third mRNA shot, is very important.

Because the vaccines were developed against the original ‘wild-type’ strain of COVID-19. Then, two shots were enough.

But as the virus mutates into Delta and now Omicron, three shots are needed to properly protect you against severe illness if infected.

2️⃣ 𝐒𝐡𝐨𝐮𝐥𝐝 𝐈 𝐬𝐭𝐢𝐥𝐥 𝐭𝐚𝐤𝐞 𝐚 𝐂𝐎𝐕𝐈𝐃-𝟏𝟗 𝐛𝐨𝐨𝐬𝐭𝐞𝐫 𝐣𝐚𝐛, 𝐢𝐞 𝐚 𝐭𝐡𝐢𝐫𝐝 𝐬𝐡𝐨𝐭, 𝐞𝐯𝐞𝐧 𝐚𝐟𝐭𝐞𝐫 𝐈 𝐠𝐞𝐭 𝐢𝐧𝐟𝐞𝐜𝐭𝐞𝐝?

Yes. Having an infection is not a substitute for taking the jab.

 

All of us react differently to the infection. So it is better for everyone to still take their booster, or a third shot. But if you are recently infected, wait for 90 days.

 

If you are very eager to take your booster, wait at least 28 days. But the effect after 90 days would be better.

3️⃣ 𝐏𝐞𝐨𝐩𝐥𝐞 𝐢𝐧 𝐭𝐡𝐞𝐢𝐫 𝟓𝟎𝐬, 𝟔𝟎𝐬 𝐚𝐧𝐝 𝟕𝟎𝐬 𝐡𝐚𝐯𝐞 𝐛𝐞𝐞𝐧 𝐨𝐟𝐟𝐞𝐫𝐞𝐝 𝐭𝐡𝐞 𝐬𝐞𝐜𝐨𝐧𝐝 𝐛𝐨𝐨𝐬𝐭𝐞𝐫 𝐬𝐡𝐨𝐭. 𝐈𝐟 𝐈 𝐚𝐦 𝐰𝐢𝐭𝐡𝐢𝐧 𝐭𝐡𝐚𝐭 𝐚𝐠𝐞 𝐠𝐫𝐨𝐮𝐩, 𝐬𝐡𝐨𝐮𝐥𝐝 𝐈 𝐭𝐚𝐤𝐞 𝐢𝐭?

Based on data for those in their 50s, 60s and 70s, protection against severe illness and hospitalisation remains very strong, 9 months after the first booster shot.

 

This is why we did not say we strongly recommend that you take the shot, but said we are offering these shots.

 

However, some could be living with the elderly, or have to travel, or have underlying illnesses that make them worried about their health, and they will want to take the second booster.

 

So judge your circumstances, and if you need to, just walk in and you will be able to take it.

4️⃣ 𝐃𝐨 𝐈 𝐡𝐚𝐯𝐞 𝐭𝐨 𝐜𝐡𝐚𝐧𝐠𝐞 𝐭𝐡𝐞 𝐭𝐲𝐩𝐞 𝐨𝐟 𝐯𝐚𝐜𝐜𝐢𝐧𝐞 𝐰𝐡𝐞𝐧 𝐈 𝐠𝐨 𝐟𝐨𝐫 𝐦𝐲 𝐛𝐨𝐨𝐬𝐭𝐞𝐫 𝐣𝐚𝐛?

All the vaccines are very good and effective, and there is no need to change the vaccine.

 

Many residents, especially seniors, may be worried about mRNA vaccines as they may have underlying illness, or experienced a bit of reaction after the second or third shot.

They can take the Novavax’s Nuvaxovid COVID-19 vaccine. It has high efficacy and is based on more traditional technology.

1️⃣ 我为什么需要打追加剂？

打追加剂，或是第三支信使核糖核酸（mRNA）疫苗，是非常重要的。

冠病疫苗最初研发时是用来对抗原始的冠病病毒。当时，两剂疫苗就够了。

但随着病毒变种成为德尔塔（Delta）变异毒株到现在的奥密克戎（Omicron），我们需要三支疫苗才可以得到更好的保护。如果还是被感染，可以减低重病的风险。

2️⃣ 我感染过冠病，还需要打追加剂吗？

需要的。被冠病感染不能取代追加剂提供的保护。

这是因为每个人被感染后，会有不同的反应。有些人会产生有效的免疫反应，有些则不会。所以，每个人还是最好都去打追加剂。

不过，最少应该要等到染疫的28天之后。最好是等上90天才接种，效果会更好。

3️⃣ 50，60和70岁的群体现在可以打第二支追加剂。如果我属于这个年龄层，我应该去打吗？

目前的数据显示，50，60和70岁的群体在接种第一支追加剂之后的九个月内，受到保护不会患重症、不需要住院的效果还是很强的。

 

这就是为什么政府没有强烈建议这个群体的人去打第二支追加剂，而是提供这个选择给那些有意这么做的人。

有些人可能因为家里有老人家，或者打算出国、或是自己目前患有某些疾病，担心感染冠病会病重等等原因，所以我们提供这些人打第二剂追加剂的选择。

所以你必须考虑自己的情况。如果有需要打第二支追加剂，你不必预约，可以直接去任何一家冠病疫苗接种中心。

4️⃣ 我去打追加剂的时候需要换疫苗的品牌吗？

所有获批准的追加剂疫苗都非常有效，所以不需要刻意选择不同牌子的疫苗。

但是，我知道有些居民，尤其是年长者，对mRNA疫苗还是有些顾虑。如果是因为有潜在疾病，或是之前打了第二或第三剂后出现一些副作用，可以考虑改打诺瓦瓦克斯（Novavax）的疫苗。

诺瓦瓦克斯的疫苗的保护力良好，而且采用的是传统的疫苗制造技术。
