The ideal vaccine should protect everyone and cause lifelong defences with a single dose. It would be quick to produce, affordable, easy to administer (nasal or oral administration) and wouldn’t need refrigeration, so non-specialists can distribute it to hard-to-reach parts of the world. In reality, we don’t fully understand how to produce a vaccine that induces long-lived protective immunity for different viruses. For some infections, we need to administer booster vaccinations.

Ageing comes with a tired immune system that struggles to respond to vaccination, and this is also the case for people with weakened immune systems, so it is difficult to protect the most vulnerable. Therefore, vaccination programmes that protect over 80% of the population can reduce the incidence of virus spreading and protect the vulnerable by proxy, through herd immunity. Currently, the percentage of people who may have had COVID-19 in different parts of the world varies, but this is hard to estimate because of test availability.

However, there is no strong evidence for any adverse effects of antibodies for SARS-CoV-2 infection.

Here are some reasons to be optimistic. One, this virus can be cured. Unlike some viruses such as HIV that embed their genome in our own and make fresh copies of themselves after immune elimination, we know that SARS-CoV-2 is unable to persist in this way.

Two, most infected patients develop antibodies and there is evidence of virus-specific T cell responses. Although we don’t know if these responses are protective yet, these are precisely the responses that can lead to immunological memory, the cornerstone of vaccination. Vaccine products will be refined and enriched to induce more potent immune responses than natural infection.

Three, coronaviruses mutate slower than viruses such as influenza, and we know from Sars and Mers that antibodies can persist for at least one to two years following recovery. This is good news for an effective vaccine that may not require updating for quite some time.

A coronavirus vaccine is within our reach, and it is our best hope to stem transmission and generate herd immunity to protect the most vulnerable. Taking away its hosts for replication, we can eradicate this virus from the human population just as vaccination previously eradicated smallpox.

According to international news agencies, a few studies about COVID-19 vaccines are promising, especially the vaccine that is being developed at Oxford University labs. Such news agencies are saying that this vaccine will be available around the end of this year or beginning of 2021. Let's hope for the best.

Thank you so much dear dr Reji Joseph

Thank you so much dear sir dr Dr-Ahmed M. Al-Baidhani د. احمد البيضاني

It is difficult to say when there will be an effective vaccine against the novel coronavirus.  It takes a long time to develop a vaccine for a new infectious disease, usually as long as 5 to 10 years. Every effort is being made to accelerate development of a vaccine for COVID-19. However, before a well-functioning vaccine can be developed, a substantial amount of research has to be done on the virus itself. In addition, the possible vaccine also needs to be clinically tested in humans for safety and efficacy. All this takes a lot of time.

Scientists test and confirm a vaccine’s safety before it is approved. We appreciate that in some viral infections, existing antibodies from an earlier infection with the same type of virus can cause more severe disease. However, there is no strong evidence for any adverse effects of antibodies for SARS-CoV-2 infection.

Not sure yet however intensive research is ongoing to develop one

Two vaccines have already passed preclinical trials. In our country, the Gamaley Institute has already released one vaccine. It operates, however, industrial capacities will not yet allow producing it in sufficient volumes. Therefore, the vaccines will not be able to be marketed until the end of the year.

Research is going on. We hope that the vaccine will discover very soon.

Thank you so much dear dr Manal Hadi Kanaan

Not yet, but it will be available soon.

There are news about clinical trials being carried out , but it's too early to judge if it's going to be approved and accepted. Every vaccine trial needs time for it to be declared safe.

Till date there is no available vaccine against COVID-19.

I agree with @Kanan madam

Only clinical trials are going. Still we have to wait some more time to get vaccine.

Based on the reports from all over the world, they are still working for the vaccine and one of them is from the University of Oxford, but, still, on clinical trials and hopefully, the end of this year, they can finalize the suitable vaccine for the COVID19. We pray for it. Thank you all, and kind regards.

Till now no vaccine available, just trials

Thank you so much dear sir dr Ronald Gomeseria

Thank you so much dear sir dr Ronald Gomeseria

Yes, it will. However, in the UK there have been development. Lets see.

Thank you so much dear sir dr Salman Bin Naeem

Till now there is no vaccine

The whole world is trying to make one. Some claim to be at the phase III trials. Lets hope we get it soon.

Thank you so much dear Sura Aldewachi

Thank you so much dear sir dr Hassan Izzeddin Sarsak

Thank you so much dear sir dr Muhammad Jawad

Good question

When a disease is new, there is no vaccine until one is developed. It can take a number of years for a new vaccine to be developed.

Thank you so much dear sir dr Falah Hasan Obayes Al-Khikani

Thank you so much dear sir dr Palem Harinath

Thank you so much for all RG members

Deaar Dr Rasha Majid Abd Ulameer Alhumairi there is no vacine is avilable but some other antiviral drugs are available for COVID-19. e.g Nucleotide and nucleoside analogue such as

Remdesivir, Sofosbuvir , Ribavirin ,

Tenofovir etc

Thank you so much dear sir dr Sikandar Khan

Many thanks to all the friends and professors for all the helpful discussions and valuable answers

Many pharmaceutical companies are working on the SARS-CoV-2 (Covid-19) coronavirus vaccine. Some of the vaccines that are currently being tested in the laboratory have been developed from plasma collected from people who have recovered from Covid-19 disease. Unfortunately, it is not known when the tested Coronavirus vaccines will be widely available to citizens. There are various forecasts in this regard, suggesting that it could be in the spring of 2021 or as late as the end of 2021 at the earliest. Greetings,

Dariusz Prokopowicz

At present, no licensed specific or particular vaccines or drugs available to treat SARS-CoV-2, but there is ongoing clinical trials of vaccines by various institutes across globe. Research is happening at breakneck speed. About 240 vaccines are in early development, with 40 in clinical trials and nine already in the final stage of testing on thousands of people. Most experts think a vaccine is likely to become widely available by mid-2021. Currently, boosting immune system and following precautionary measures and SOPs are the only way out.

Again, international news agencies still saying that the development of a few COVID-19 vaccines is under progress and that these vaccines are promising, especially the vaccine that is being developed at Oxford University labs. They add that these vaccines will be available around the end of this year or beginning of 2021.

^^ According to Covid-19 Vaccine Tracker: more than 18.9 million shots given.

^^ According to Covid-19 Vaccine Tracker: more than 60.3 million shots given (7:00 AM CET 23/1/2021).

It take number of years for vaccine to be developed for new viruses, mostly it is dependent on the availability of infrastructure and scientific facilities.

Currently (February 2021), there are already several SARS-CoV-2 (Covid-19) coronavirus vaccines in operation on a global scale, manufactured by several pharmaceutical companies and used in vaccination programs for citizens. Among others, vaccines from the following companies: Pfizer, Moderna, Astra-Zeneca, Sputnik vaccine etc. are already used in min. several countries in citizen immunization programs. Over the next few months, several more vaccines will appear. For example, a vaccine from Johnson & Johnson and several more companies will soon be available. In connection with the above, in mid-2021, up to a dozen vaccinations produced by various pharmaceutical companies may be used in the vaccination programs of citizens on a global scale. Thanks to the high production capacity of these pharmaceutical companies, it will be possible to vaccinate most of the human population on a global scale in 2021. In this way, it is possible to solve the problem of the SARS-CoV-2 (Covid-19) coronavirus pandemic in the current 2021.

Recently it is not available

There are now several vaccines for coronavirus. I think their development will now be ongoing. In a few years, they will become common practice like flu shots.

No

There are currently many vaccines for Covid-19. There is a program that has been around for this very reason. It allows scientists to get right on making and releasing a working vaccine quickly in the presence of things like a pandemic.

Now,there r different types of vaccine ,pfizer,Astrazeneca,Sinopharm,ghonson-ghonson&others(Turkish&Russian types) for novel corona virus.

Not yet.

There are now many vaccines. There is even a booster.

Yes. Please consult the following RG link for details.
