中國疫苗安全性高，對變種病毒有效！坡島網友：再不審批通過就過期了！

萬事通說

一波未平，一波又起……難道待在家裏也不安全了嗎？

萬事通每天都會在後台收到大量通心粉的留言，內容都是靈魂拷問：新加坡到底啥時候才能通過中國的科興疫苗的審核？啥時候才能接種中國的科興疫苗？

更有網友甚至給新加坡想了三點建議：1.停止印度新加坡航班。2.通過中國疫苗，加快接種速度。3。全民檢測。

但是就在大家的翹首以盼之中，卻遲遲沒有等來中國科興疫苗通過審批可以注射的消息……

隨著疫情在新加坡社區的蔓延，如今不僅在新加坡的中國人坐不住了，很多醫生也坐不住了！紛紛發聲希望中國科興疫苗能盡快通過審批。

網傳新加坡醫生們的公開信希望盡快批准滅活疫苗

最近，新加坡的社交媒體上廣泛流傳了一份醫生的公開信，公開信內容如下：

*An open letter to all parents deciding to vaccinate or not to vaccinate their child.*
We are a group of Singaporean Doctors, who are of the view that MOH should quickly approve a killed-virus vaccine for our children and adults. Here are our humble ponderings:
1/ Children: 99.99% do not need ICU when they catch Covid-19. According to a Senior Pediatrician (Dr Chandra Sekhar Devulapalli), this is likely due to NL63, an almost universal childhood common cold. This immunity is likely to be present in younger Singaporeans in the form of Memory T-Cells. Unfortunately, it wears out by about age 65. This explains why the population above this age frequently populates our ICU when they become very sick with Covid-19. The good news is that Children are doing amazingly well, without any Covid-19 vaccines.
2/ The two mRNA vaccines have been vigorously tested to be safe, but we know this is true only for the short term. We have no evidence that the mRNA vaccines are SAFE in the longer term (10-20 years). This is not a problem with those over 65, as the immediate benefits of vaccination for this high-risk group outweigh the risks of the unknown long-term side effects. For Children, however, it is another matter altogether.
3/ mRNA themselves are very fragile in the human body and are easily attacked by Ribonucleases that are distributed very widely in our body. Reverse Transcriptase, which converts RNA to DNA, is very troubling. It is not naturally found in our body but becomes readily available if you are very sick with a chronic virus, like Hepatitis B. Our local population has significantly higher rates of Hepatitis B (about 3.6% – many of the infected are unaware) and many are still undetected. Relying on data from a population that is significantly different from our local population is NOT very wise.
Please refer to the article: https://pubmed.ncbi.nlm.nih.gov/33330870/
4/ mRNA vaccines do not stop adults from transmitting Covid-19-VOC. We can assume that this will also be the case with children.
5/ It is NOT very WISE to try on Singaporean Children with Novel mRNA technology when they do not really need it and it DOES NOT effectively STOP them from becoming VECTORS.
6/ Killed-Virus technology has been around for decades and has a very long and safe track record. We even have thousands of it in our local warehouse at this moment and it had just been tested to be safe at Phase II/III for children (550 subjects).
Please refer to the article: https://abcnews.go.com/Health/wireStory/sinovac-vaccine-safe-children-young-76624380
7/ We feel a lot safer, with KNOWN technology (proven to be SAFE), since our children are likely to outlive us. Primum non nocere.
8/ For mRNA, long-term side effects are unknown and unstudied. This point is supported by all Experts.9/ These are our humble opinions. We hope MOH will allow parents to pick a vaccine that has been proven to be safe (ie, with no long-term harmful side effects) for our children and grandchildren.
Let us as a community, stand together and overcome this pandemic, with wisdom and prudence. Vaccination will drastically reduce the severity of Covid-19 infection for the vulnerable and will save many lives. We are very grateful for the availability of Vaccines made available by the determined effort of the MTF. Provideing us an option for a killed-virus vaccine would be most appreciated.
Yours Sincerely,
Dr Benny K H Tan (MCR 01588A)Dr Chia AM (MCR M02673E)Dr Clement Lai (MCR M04559D)Dr Colleen Thomas (MCR M05352Z)Dr CT Tan (MCR M01740Z)Dr Diane Jek (MCR 09198G)Dr Judy Chen (MCR 05364C) Dr Kee Leng Chee (MCR (M01006E)Dr Kho Kwang Po (MCR 00499E)Dr Khoo Boo Kian (MCR 03808C)Dr Paul IW Yang (MCR 08851z)Dr Suzie Lee (MCR M05023G)

這封公開信主要提到，目前新加坡接種的疫苗采取的是mRNA技術，長期副作用尚不明朗，而中國疫苗采取的病毒滅活技術可能更安全、有效，尤其是現在新加坡兒童感染人數很多，這時候更應該給孩子選擇一款安全的疫苗。
大家都知到，目前新加坡可以接種的疫苗是美國的輝瑞和莫德納，它們都屬于mRNA信使核糖核酸疫苗，中國目前的國藥和科興疫苗則屬于滅活疫苗。
全世界有能力研發疫苗的國家中，只有中國研發滅活疫苗。而相對于mRNA技術是一種全新的技術，滅活疫苗已經是非常成熟的技術，
中國疾病預防控制中心專家認爲，中國滅活新冠肺炎疫苗對多數變種病毒株仍然有效。

面對新型冠狀病毒變種病毒株，中國的滅活疫苗在全球大規模、涉及大量人群的研究中都有效。現有疫苗對之前英國變種病毒的保護力沒有問題，在印度發現的病毒株雖然是剛發現的，但從變異的數量來看，並沒超過巴西和南非的變種病毒，印度科學家也做了一些測試，認爲現在使用的滅活及病毒載體疫苗仍然有效。

中國疫苗接種數全球第一在巴西小鎮創下奇迹

目前全球新冠疫苗接種已經超過15億劑次，其中近六成集中在中國、美國和印度。其中中國共接種了超5億劑，接種數量全球第一。

除此之外，中國疫苗的有效性也得到了證明。在巴西有一個僅有4.5萬人的小鎮塞拉納。它曾感染率高達10%，當地醫療系統不堪重負。絕望之際，當地官員做出了一個大膽的決定：全鎮集體接種中國科興的新冠疫苗。

除了未成年人、孕婦和最近發燒的人，全鎮4.5萬人口裏，約有2.77萬人符合接種標准。在嚴峻疫情的壓力下，塞拉納小鎮的居民們，幾乎全部都同意接種。
最後實際完成兩針疫苗接種的人數爲2.72萬，接種率占目標人群的98%，占全鎮人口的60%。

據中國衛健委專家所說的一般標准，建立全民免疫屏障，疫苗接種率需要達到60%-70%。塞拉納，剛剛好達到了這個標准。
讓人驚喜的是，在接種科興疫苗之後，塞拉納的新冠病毒感染率下降了75%！完成兩針疫苗接種的人群裏，沒有1例因新冠導致死亡！這些數據都證明了中國疫苗的有效性！
不僅巴西小鎮居民證實了中國科興疫苗的有效性，泰國高等教育與科研創新部官員也透露，研究發現，有65.9%的科興疫苗接種者在接種第一針的三周後就出現免疫反應，完成兩劑接種的四周後，比例高達99.49%。這名官員表示，科興疫苗在增強對冠病病毒的免疫方面非常有效。

網友質疑：再不通過審批科興疫苗就要過期了

如今新加坡社區疫情這麽嚴重，在世界各國都已證明中國疫苗的安全性和有效性都不錯的情況下，大家希望新加坡趕緊審批通過中國科興疫苗的心情越來越迫切。
大家都知道2021年2月23日，中國科興疫苗就已經運抵新加坡了，但是一直到3個月後的今天科興疫苗仍然未批准使用。
對于遲遲不批准科興疫苗這事兒，新加坡衛生部表示還在評估科興疫苗的安全和有效性，還在等待疫苗制造商呈交更多數據，還有留意該疫苗在其他國家的使用情況。

一直在審批，很多網友都擔心，運來新加坡的這批科興疫苗會不會過期呢？這一點大家不需要擔心，科興疫苗有長達兩年的保質期限。
希望新加坡能夠加快評估科興疫苗，加快新加坡的疫苗接種速度，盡快形成群體免疫，早日恢複正常生活。
