Naibu Waziri wa afya Dkt. Mollel amesema chanjo ya Corona ni salama ndio maana Rais Samia mara tu baada ya kuchanjwa aliweza kuendelea na shughuli zake kama kawaida.
Mollel amesema Rais Samia alitoka Ikulu baada ya kuchanjwa na kwenda Lugalo Hospital ambako alifanya ukaguzi na kufungua mradi wa afya kisha akahutubia.

Chinese vaccine producers Sinovac and Sinopharm have signed on to global vaccine sharing scheme Covax, which aims to distribute vaccines to poorer countries.
The Global Alliance for Vaccines and Immunization (Gavi) said it would make 110 million doses of the vaccines available as part of the scheme.
Covax has agreements with the manufacturers of 11 vaccines and plans to provide 2 billion doses across the world by early 2022.
Both Sinopharm and Sinovac, which have been approved by the World Health Organization (WHO) for emergency use, are already being used in China and dozens of countries around the world.

How does the Sinovac vaccine work?
The Beijing-based biopharmaceutical company Sinovac is behind the CoronaVac, an inactivated vaccine.
It works by using killed viral particles to expose the body's immune system to the virus without risking a serious disease response.
By comparison the Moderna and Pfizer vaccines are mRNA vaccines. This means part of the coronavirus' genetic code is injected into the body, triggering the body to begin making viral proteins, but not the whole virus, which is enough to train the immune system to attack.
"CoronaVac is a more traditional method [of vaccine] that is successfully used in many well known vaccines like rabies," Associate Prof Luo Dahai of the Nanyang Technological University told the BBC.
On paper, one of Sinovac's main advantages is that it can be stored in a standard refrigerator at 2-8 degrees Celsius, like the Oxford vaccine, which is made from a genetically engineered virus that causes the common cold in chimpanzees.
In contrast Moderna's vaccine needs to be stored at -20C and Pfizer's vaccine at -70C.
It means that both Sinovac and the Oxford-AstraZeneca vaccine are a lot more useful to developing countries which may not have the facilities to store large amounts of vaccine at such low temperatures.
