Despite the government’s pledge that all long-term residents will be able to get free vaccinations, more than half of them are on the fence about such benefits.
Everyone wants to see “how others react” and is afraid of getting a shot for nothing and side effects, after all, this is a special time to rush to the shelves of a batch of vaccines.
More recently, mass vaccinations have been completed in some hard-hit areas, and more clinical test data have been made public.
The efficacy of Sinovac vaccine is 91.25%
Fewer side effects
Since the middle of September, Beijing Sinovac has started phase III clinical trial in Turkey. Three months have passed. What is the effect of the vaccine?
Are there any serious side effects?
Turkish Health Minister Fahrettin Koca said on the evening of 24th:
Turkey has determined that the Beijing SINovac inactivated vaccine is effective and safe for the Turkish population.
At a news conference, Corker said:
A preliminary analysis of data from 1322 Turkish volunteers who volunteered to receive the vaccine showed that the vaccine was 91.25% effective, and no serious side effects were found during the clinical trial, except for one person who experienced an allergic reaction.
Some common adverse reactions are fever, mild pain, and mild fatigue.
The third phase of the Turkish test has not yet been completed, with a total of 7,371 volunteers. The figures are based on 1,322 volunteers.
Turkey, which has 2.2 million confirmed COVID-19 cases out of a population of about 83 million, is in urgent need of vaccine support.
Another 3 million doses of the vaccine will be sent from China to Turkey on December 27, and Turkey will purchase another 50 million doses after that.

Hong Kong, China Experts:
Sinovac vaccine has fewer side effects
Suitable for the elderly
Professor Yuen Kwok-yung, Chair professor, Department of Microbiology, University of Hong Kong, China, is Hong Kong’s leading expert on infectious diseases.
Yesterday (25 December), he wrote in a newspaper that the fourth wave of COVID-19 in Hong Kong was causing difficulties in community prevention and control, as well as a lack of strict enforcement of social distance, making it urgent for Hong Kong residents to get vaccinated.

He also compared three types of vaccines that Hong Kong was interested in buying — Pfizer, Sinovac, and Astrazeneca and Oxford.
Data from phase I and Phase II studies of the inactivated sinovac vaccine showed low side effects, with fever after injection being 3.3 per cent, 14.2 per cent for Pfizer and 18 per cent for Astrazeneca, said Prof Yuen.
If the elderly or the sickly have a fever, it is likely to cause cardiovascular and cerebrovascular complications, heart problems, so these people are suitable for injection of sinovac inactivated vaccine.
Of all the vaccines currently on the market, Sinovac appears to be the safest, acceptable to the elderly and the chronically ill.
The sinovac vaccine does not need to be stored in low temperature, so that private doctors can bring the vaccine to the home for the elderly to be vaccinated.

New York Times:
American doctors vaccinate Modena
A severe allergic reaction occurs
Currently, two vaccines have been approved in the United States, the Merck vaccine and the Pfizer vaccine.
Yesterday, a story in the New York Times got a lot of attention.

Hossein Sadrzadeh, a middle-aged and elderly oncologist at Boston Medical Center, reportedly developed a severe allergic reaction within minutes of receiving the Moderna vaccine on December 24:
“Feeling dizzy, dizzy, racing heart, tongue numbness, blood pressure plummeting and breaking into a cold sweat. I don’t want anyone to go through that again…”
He was taken to the emergency room for treatment and observation and has since recovered and been released.
Plastic surgeons who get vaccinated may have swollen faces
Plastic surgeons should be careful when choosing vaccination!
Recently, the Us Food and Drug Administration (FDA) committee reminded the public:
People who have had plastic surgery (lip augmentation, microsurgery, facial fillers, etc.) may experience swelling and inflammation of the face as side effects of the Modena vaccine.
It’s a mechanism by which the body’s immune system, which fights inflammation, revs up, and symptoms disappear after treatment with drugs, according to dermatologists.
Singapore Vaccination Programme:
What’s the difference between the three
Earlier, Prime Minister Lee Hsien Loong said in a televised speech:
Vaccines to be used in Singapore include Psion-Biontech Moderna SinoVac.
[The Straits Times]
These vaccines are currently internationally recognized as effective and safe, and the authorities hope that all long-term residents of Singapore aged 16 and over will be able to get vaccinated against COVID-19.
What’s the difference between them?
The storage requirements of the three vaccines are different:
Pfizer’s most expensive vaccine must be stored at minus 70 degrees Celsius.
Better yet, the storage temperature must be minus 20° C;
Sinovac inactivated vaccines are very grounded, as long as they are kept at normal refrigerator temperatures (2° to 8°).
Both The Merck and Pfizer vaccines are RNA vaccines, which are made by taking a portion of the RNA encoded protein from the virus and making them easier to manufacture.
The sinovac inactivated vaccine, made using traditional methods, is considered safe and can be administered even to people with weak immune systems.
The RNA vaccine is a new type of vaccine. There have been no successful mass vaccinations yet, but inactivated vaccines, such as rabies, are widely used and very successful, said Lo Dahai, associate professor of infection and immunization at Nanyang Technological University in Singapore.

The interval between the two inoculation is different:
The interval between the first and second doses was 28 days.
The interval between the first and second Pfizer vaccine was 21 days.
The interval between the first and second sinovac inactivated vaccine was 14 days.

Obviously sinovac is a little bit more down to earth?
But because Pfizer’s vaccine is the first to be declared effective and introduced on a large scale, it is now more widely accepted internationally than the other two.
