The U.S. Food and Drug Administration issued a statement a few days ago, approving local children from 6 months old to 5 years old to receive the new crown vaccine from Pfizer and Moderna Pharmaceuticals.
Cui Junming, president of the Hong Kong Society of Hospital Pharmacists, said today (21st) that according to U.S. data, the dose of 6-month-old to 4-year-old children is 1/10 of the adult dose of Fubitai vaccine. If you want to extract 0.03 ml of vaccine from the adult dosage form , requires certain technology, and the error is large, so it is recommended that the government at least purchase the new crown vaccine dosage form specially designed for children aged 5 to 11.

Once the risk of infection is high for infants and young children under 4 years old, Cui Junming agrees to lower the lower limit
Cui Junming said on the Hong Kong and Taiwan program "Millennium" today that infants from 6 months old to 4 years old belong to a high-risk group. Once infected with the new crown or influenza virus, there is a higher risk of complications such as pneumonia or meningitis. Therefore, I agree that Hong Kong follows the US practice and lowers the minimum age for vaccination against COVID-19 to 6 months.
He also explained that the Fubitai vaccine is divided into three dosage forms in the United States, including 0.3 ml for adults, and dosage forms for 5 to 11 years old and 6 months old to 4 years old.
At present, the vaccine for children aged 5 to 11 in Hong Kong is vaccinated from 0.1 ml of the adult dosage form, but for children aged 6 months to 4 years old, 0.03 ml is extracted.

Fubitai is divided into three dosage forms to draw the specified dose from the adult dosage form to the child or there may be errors
He said that according to the experience of the medical profession, at most, only 0.05 ml of vitamins have been extracted for infant vaccination, and a dose of less than 0.05 ml has never been extracted.
He explained that it can be done by extracting 0.03 ml, but it requires certain skills and the error is also large.
However, if it is extracted from the dosage form of 5 to 11 years old, 0.06 ml can be extracted, which is believed to be accurate, so he believes that "it is necessary to wait for the safety of the children's dosage form".
Cui Junming also pointed out that if a slightly larger dose is taken out, it is not a problem, and the side effects are similar, mainly muscle pain and fatigue.
However, if the extracted dose is less than 0.03ml, I am worried that it will not stimulate the immune system to produce enough antibodies.
He Bailiang urges the Hong Kong government to start negotiating with pharmaceutical companies to purchase the children's dosage form of Fubitai
He Bailiang, director of the Center for Infection and Infectious Diseases at the University of Hong Kong, said in the commercial program "Let's Go on a Sunny Day" that medical experts on the US Food and Drug Administration's select committee unanimously agreed to lower the vaccination threshold. Safety data will be published inside.
He also pointed out that the Hong Kong government should start negotiating with pharmaceutical companies, because Hong Kong has not been able to successfully purchase vaccines in children's dosage forms, and it has to extract doses from adult dosage forms, which is not strictly in accordance with the standards of pharmaceutical companies. He also questioned the claim that the main reason is related to the market. , which means that the Macau market is similar to Hong Kong, but both can successfully negotiate.
