The third or booster dose of vaccine is needed to take out the Omicron variant. The UK Health Security Agency analyzed data from 581 Omicron cases and thousands of Delta cases to calculate how effective vaccines such as Pfizer and Astra Zeneca were against the Omicron variant. This early analysis shows a third booster dose prevents around 75% of people from getting any coronavirus symptoms. The double dose of the vaccine however provides good protection against severe coronavirus that needed hospital treatment says the UK Health Security Agency. Of equal concern is the rate of spread of the Omicron variant. Here this BBC report shows graphs of UK National Health Security Agency which show the rate of spread is rapid with cases doubling every 2-3 days. For the UK which on December 10 had about 1265 cases this means says this BBC report that the number of Omicron cases could be well above 100,000 in the UK by the end of December. The BBC graph shows the curve for Omicron cases moving in a close to vertical direction upwards. Reports say the experience in South Africa where the Omicron variant was first detected is similar in pattern causing rapid spread. ...

Israel remains a laboratory for the rest of the world in tackling coronavirus. During the beginning of 2021 Israel was the first country to push ahead with Pfizer vaccines for the over 18 population in a country of 10 million people. As winter approaches Israel has given a third booster shot to 50% of the population and is able to conduct normal life with a green pass system and the use of masks indoors. Each time a major surge has been prevented. The green pass in Israel is now for people who have had a third shot or booster shot. By thinking one step ahead, making decisions rapidly, and coordinating action early between the government and other organizations to vaccinate everyone, Israel provides lessons for the rest of the world. Not that there are no unvaccinated -about 700,000 people do not believe in vaccination and are unvaccinated. They are a vocal group but only about 8% of the population, and the vast majority of Israelis are in favor of vaccination and the green pass system. ...

European Union countries reopen for travel this summer. A new travel pass or digital Covid certificate is approved to promote freedom of travel as more people get vaccinated. About a third of people are vaccinated for first shot in France and about 40% in Germany, which means in coming weeks they will have the second shot and enough antibodies to make a return to normal life possible. The EU has negotiated this time with Pfizer for 1.8 billion doses and is building enough vaccine supplies. For the first time governments are stepping up with plans and resources allocated - in India the government now has plans to create supplies of 2 billion doses by the end of the year. This means there is new hope if the vaccination is accompanied by efforts to build booster shot supplies this time planning ahead. Managing the risk of those who are vaccine skeptical remains a problem to be tackled. Masks and other essential precautions also need to be followed in crowded spaces as this was neglected where there was a second or third wave. Public education for this is essential to better manage the pandemic. ...
