FACTS! COVID-19 vaccine offers only 50% protection after first dose and 95% after the second dose!

-

 It is a word of caution for people who think that once they have the COVID-19 vaccine, they are protected. Many health care workers and those who take the COVID-19 vaccine have tested positive for the virus days after the first of the two doses of the covid-19 vaccine. Matthew W, an ER nurse from California is one such vaccine who became ill after 6 days of the Pfizer-BioNTech vaccine. What could be the reason for it?

Matthew W and his coronavirus history

On 18 December 2020, Matthew W, an ER nurse at two different local hospitals of California had received the Pfizer-BioNTech vaccine along with his fellow health care workers. He had posted a message about it on his Facebook page. He had told later ABC 10News that his arm had felt sore for a day. But besides that, he got no other ill-effects of the vaccine.

On Christmas Eve, Matthew, 45 completed his duty in a COVID-19 unit and then fell ill. First, he had chills and later severe muscle aches and fatigue. A day after Christmas, he drove up to the drive-by hospital testing center and got himself tested for COVID-19. His result came back as positive.

What experts say?

Dr. Christian Ramers is an infectious disease expert at the Family Health Centers of San Diego. He is also on the clinical advisory panel of the country’s national rollout program. He states:

"It's not unexpected at all. If you work through the numbers, this is exactly what we’d expect to happen if someone was exposed,"

He added that he is aware of several such cases in the local area who got infected around the same time that they received the first of the two vaccine dose of the vaccine. But he reveals that it is known that the protection from the vaccine is not immediate. Also, the cases might have got infected before they got the vaccine since the incubation period of the virus is around 10-14 days. Even if Matthew got the infection after the first vaccine dose, it is still at the time that the vaccine protection was not in. Also, even when the protection comes, it will not be full protection. Explaining more on it, he said:

"That first dose we think gives you somewhere around 50%, and you need that second dose to get up to 95%,"

"We know from the vaccine clinical trials that it’s going to take about 10 to 14 days for you to start to develop protection from the vaccine,"

Dr. Christian states that one should not be over-optimistic of the ability of the vaccine on turning the pandemic around:

"You hear heath practitioners being very optimistic about it being the beginning of the end, but it’s going to be a slow roll, weeks to months as we roll out the vaccine," 

He reminds that handwashing, hand hygiene at all times, face masks, and other covid-19 protocols should be continued even after the vaccine.

The take-home messages

Matthew reveals that he is feeling better now and has only mild fatigue at the moment. But his condition was bad during Christmas time. So what does all this tell us?

1.      Do not think that the vaccine will give you full and immediate protection from the virus

2.      Your symptoms may still come if you are infected before, during, or sometime after taking the vaccine.

3.      The vaccine offers 50% protection after the first dose and 95% protection after the second dose administered three months later. This implies that in 5% of the vaccinees, there might be no protection even at the end of 2 doses.

4.      The vaccine starts showing some immune response only after 2-3 weeks of administration.

5.      Handwashing, hand hygiene, face masks, and other covid-19 protocols should be adhered to even after the vaccine is taken.

Morton's toe: Everything you need to know about your longer second toe

 Often, one notices that the second toe of some people is longer than the great toe. People say different things for it. Many of them say that it implies that the owner of such a longer second toe is a dominant, creative, energetic person in real life and very ambitious and peace and happiness-loving. But no one has tried to understand the reason, science, medicine and problems of having such a toe. It is called as Morton’s toe or Greek foot.  What is a Greek foot? Many people in the world have a longer second toe of the foot. Such feature may be on one side or in both the feet. It is called Morton’s toe or Greek foot. The other names for it are Morton’s foot or royal toe. But the reason is not the second toe is longer but the fact is that the first metatarsal below the great toe is shorter. Thus it is not due to the faulty phalanges but due to the difference in height of the metatarsals. Since the second metatarsal is relatively longer than the first metatarsal, the joint at ...

Loneliness is a growing epidemic especially during this coronavirus pandemic in the USA!

  The coronavirus pandemic has increased social segregation and this has proven to be bad particularly for the elderly population. They are unable to catch up with their children and grandchildren and are finding themselves extremely lonely. They are the worst affected by the pandemic in terms of physical as well as emotional health. THE OLD AGE AND LONELINESS Old age is a time of loneliness for many people. Usually, people have lost their partners at that ripe age and depend on their children and grandchildren for support and to beat the loneliness. Though their younger family members used to occasionally visit the parents, now with the coronavirus pandemic this has become difficult due to the risk of the children carrying the infection to their aged parents and grandparents. So the visits have come down drastically and the contact remains only on phone or via digital technology. This though good does not suffice and cannot substitute the physical visits and the warmth that th...
