有冇7/10照流感咁誇張呀? 7/10普通傷風感冒就唔奇, 7/10流感我絶對唔信

How vaccines are formulated & What went wrong in 2017
The formulation for a vaccine to immunise against all four flu viruses was decided back in September 2016 and the final product released seven months later. Commonly, each virus is amplified by injecting well-growing “seed” virus into vast numbers of fertilised (embryonated) hens’ eggs. Fluid containing lots of new virus is removed, the virus is inactivated and the new vaccine is manufactured.
It’s difficult to predict what strains will dominate months later. Viruses within each flu type also change over time so H3N2 from years ago differs from H3N2 in 2017. These mutations reduce the effectiveness of flu vaccines.
Over the past year, H3N2 mutated after it was chosen as a vaccine strain. Additionally, the egg-grown H3N2 vaccine virus strain changed during vaccine production. For both these reasons, the vaccine no longer matched what we faced.
What she said I would personally disagree is: 老人家低抗力弱 SHOULD get vaccination, and people who suffer from asthma & respiratory diseases SHOULD also do so.
哇...咁你都幫佢兜呀? 如果個錄音係容祖兒GROUP流出
睇你講唔得番同一番說話 ...
