Till now, no Omicron case detected in Haryana. The state government is geared to combat the spread of Omicron variant and also to deal with any surge in the number of Covid cases. As many as 3,11,86,292 vaccine doses have been administered in the state till December 19.
In my opinion, booster is a must. When you've two doses of any vaccine your protection level, especially after 3 to 6 months goes down. If you have a third dose or a booster then the chance of having a severe infection, hospitalization reduces.
Covid always comes with mild symptoms in the initial stages. We're watching any change in the pattern of the presentation of the emerging cases very carefully.
