William Chui Chun-ming, President of the Society of Hospital Pharmacists, on Wednesday said there was no evidence that current vaccines are ineffective against the new Covid-19 variant Omicron. Speaking on a radio program, the pharmacists' group head said that although there were mixed messages over vaccines' effectiveness against the new variant, he anticipated that existing vaccines could still offer protection. Chui said the vaccines would not only stimulate the human body to generate antibodies against the virus but also trigger immune responses to generate immune cells that can attack infected cells, providing a certain degree of protection. He expected that it would take pharmaceutical companies around half a year to produce vaccines targeting Omicron. He added it would only take another three months for the companies to bring the new version of the vaccines into mass production and ready for distribution.
