PHUKET: The Ministry of Public Health began on Friday the intradermal vaccination against Covid-19 as a booster in this southern province, saying that a normal dose could be stretched to inoculate five times more people than by intramuscular injection.
Dr Withita Jaeng-iam, deputy director of Vachira Phuket Hospital, said the intradermal injection started in Phuket with the Covid-19 vaccine made by AstraZeneca as the third booster injection.
The skin injection was administered at six local inoculation stations with a combined capacity to vaccinate more than 8,000 people per day, she said.
Intradermal injection used one-fifth of the dose normally given to a person by intramuscular injection. Therefore, the vaccination could cover more people faster, said Dr Withita.
Both Thais and foreigners were very interested in intradermal injection, Dr Withita said.
Local and international research has shown it to be as effective as intramuscular injection and with fewer side effects, according to Dr. Withita.
