How Many Covid 19 Vaccines Are There

Vaccine Development: Vaccines Approved For Use And In Clinical Trials

There are four types of COVID-19 vaccines: heres how they work

The speed at which the first COVID-19 vaccines were developed was extraordinary. We have previously looked into the history of vaccine development. The measles vaccine was found relatively rapidly: it took only 10 years from the discovery of the pathogen to the development of the first vaccine. But for typhoid it took more than a century, and for some diseases for which weve known the pathogens for more than a century we still havent found an effective vaccine.

The development of a vaccine against COVID-19 has been much faster than the development of any other vaccine. Within less than a year several successful vaccines have already been announced and were approved for use in some countries.

The hope is that even more manufacturers develop vaccines for COVID-19. This will be important because eventually a very large share of the world population needs to receive a COVID-19 vaccine.

We are on the way to several vaccines against COVID-19 vaccine trackers monitor the progress:

Several institutions maintain websites on which they list COVID-19 candidate vaccines that are currently being developed:

Oxford/AstraZeneca, Sinopharm/Beijing, Sinovac, Sputnik V

What Is The Difference Between Emergency Use Authorization And The Normal Process Of Vaccine Approval

The main difference between emergency use authorization, or EUA, and the normal process, which is via a biologic licensure application, or BLA, is how long data were collected prior to the vaccines being reviewed for use. So, when considered quite literally, the vaccines being used today will be no different than those that are being used the day after the vaccines get full approval . The reason for the shortened timeline was, of course, because of the pandemic. But, at this point, the vaccines have been given safely to millions of people and the companies have been monitoring vaccine recipients for months. As such, at this point, delaying vaccination until the vaccines get full approval is taking an unnecessary risk.

Is It Safe For My Adolescent Or Teen To Get The Covid

The Pfizer COVID-19 mRNA vaccine is approved for those 5 years of age and older. Other COVID-19 vaccines are still being tested in those younger than 18 years of age.

When the Pfizer vaccine was tested in 5- to 11-year-olds, it was found to be safe:

  • More than 15 million teens between 12 and 18 years of age had received one dose of COVID-19 vaccine, and more than 12.5 million had received both doses by Nov. 9, 2021.
  • The clinical trial in 5- to 11-year-olds evaluated about 1,300 children who received the vaccine and compared them with about 660 children who got placebo . Three vaccinated individuals got infected with COVID-19 compared with 16 in the placebo group . Side effects were similar to those in older children and adults, including pain, swelling and redness at injection site fever tiredness headache muscle aches chills and occasionally, swelling of the under arm on the side the vaccine was given. However, children tended to experience side effects less often and those with previous infection were less likely to experience side effects.

No cases of myocarditis were identified in the clinical trial however, because the trials were small, it will be important to monitor for this rare, but serious side effect when more children are immunized.

If I Have Already Had Covid

Everyone should be offered the COVID-19 vaccine, regardless of whether they have already had the infection previously. However, those who are currently infected with COVID-19 should postpone vaccination until after their illness has run its course and after they have met their health authorities criteria to discontinue isolation.

Given that persons who have had COVID-19 develop immunity for at least a few months following illness, health authorities may decide to postpone their vaccination to use their current supply for those not yet affected by the disease and until more vaccines become available.

Vaccinations Uptake By Ethnicity


This table is a person view.

* The prioritised ethnicity classification system allocates each person to a single ethnic group, based on the ethnic groups they identify with. Where people identify with more than one group, they are assigned in this order of priority: Mori, Pacific Peoples, Asian, and European/Other. So, if a person identifies as being Mori and New Zealand European, the person is counted as Mori. See Ethnicity Data Protocols for further information.

Ethnicity breakdown by DHB of residence is available in the downloadable spreadsheet at the bottom of the page.

The Eu Vaccine Strategy

With the EU Vaccines Strategy, the EU is supporting efforts to accelerate the development and availability of safe and effective vaccines in a timeframe of less than one year for most vaccines.

The Commission entered into advanced purchase agreements with individual vaccine producers on behalf of the Member States, and secured more than 4.2 billion doses of vaccines for European citizens and for countries around the world where vaccines are less available.

Can I Get The Second Dose Of Covid

Yes. It is okay to get the second dose in the other arm as the immunity generated by the first dose will be circulating in your body watching for a potential exposure.

Indeed, individuals who experience a delayed reaction at the injection site are recommended to get the second dose in the opposite arm.

What Are The Leading Covid

Most of the vaccines approved for at least limited use have been developed by firms and research groups in China, Russia, and the United States.

Scores of other COVID-19 vaccine candidates are undergoing large-scale clinical trials and around two hundred potential vaccines are in preclinical development by pharmaceutical companies, academic institutions, and government agencies.

Can Vaccines End The Pandemic

How the COVID-19 vaccine trials work

Even with a variety of vaccines with at least limited approval, there remains the tremendous challenge of making enough and distributing them to the global population. Though multilateral initiatives such as COVAX and individual governments are investing billions of dollars to expand production plants, current global manufacturing capabilities are far below whats neededonly about a dozen countries have the capacity to produce COVID-19 vaccines.

This task has not only motivated countries to scale up production, but also pitted them against one another amid a limited vaccine supply. Wealthy countries including Australia, Canada, and the United States struck deals with manufacturers early on to provide their own countries with more than enough doses, leaving lower-income countries unable to immunize but a small proportion of their citizens. China and India have large vaccine industries, which allows them to reserve some of their vaccine supplies for their own populations. Experts including CFRs Thomas J. Bollyky have warned that bidding wars over vaccines lead to inequitable distribution and, ultimately, fail to eliminate the risk of new outbreaks. WHO Director General Tedros Adhanom Ghebreyesus has echoed this, asserting that the world must end vaccine inequity to end the pandemic.

What Are Cvst And Thrombocytopenia

Cerebral venous sinus thrombosis is a condition that causes blood clots in large vessels that drain blood from the brain. Although it is uncommon, the condition more often affects women between 20 and 50 years of age.

Thrombocytopenia is low numbers of cells called platelets. Platelets are cells that help our blood clot. When a person has this condition, they are at risk for bleeding since their body lacks the ability to efficiently stop the bleeding.

It is very uncommon for CVST and thrombocytopenia to occur at the same time, which is what makes this diagnosis following receipt of the J& J vaccine so unusual. Likewise, the clots have not just occurred in the large vessels near the brain in some of the affected individuals.

Who’s Eligible And How To Book

All vaccines approved for children require 2 doses at least 8 weeks apart to be fully protected. Minors under 18 require verbal or written consent from a parent or guardian to be vaccinated.

Children 12 and older

  • The children’s dose is 1/3 of the regular vaccine .
  • It is 90.7% effective in preventing illness and no serious side effects were identified.
  • Children are recommended to wait at least 14 days between the COVID-19 vaccine and the seasonal flu vaccine. Routine school immunizations can continue as scheduled.
  • Children under 5

    Is It Safe To Get A Covid

    COVID-19 vaccines may be administered to people with underlying medical conditions provided they have not had a severe or immediate allergic reaction to any of the ingredients in the vaccine. In the context of limited supply vaccination is recommended as a priority for persons with comorbidities such as chronic respiratory disease, chronic cardiovascular disease, obesity and diabetes, all of which have been identified as increasing the risk of severe COVID-19 disease and hospitalization.

    When Can I Expect To Receive My Vaccination

    How many people need to get a COVID

    There is a massive global demand for COVID-19 vaccines and vaccine supply is still limited which means that not everyone will be able to get the vaccine at the same time. All countries need access to safe and effective COVID-19 vaccines and within countries the first batches of vaccines need to be given first to the people who are at highest risk of infection, serious disease, or death. This includes health workers who care for COVID-19 patients, older adults and subsequently people with certain underlying health conditions.

    Is It Necessary To Wait To Get Blood Work Done After Getting The Covid

    Generally speaking, it would be recommended to wait about a week after getting the mRNA vaccine and a few weeks after getting the adenovirus-based vaccine before getting bloodwork. However, it would be better to inquire with the healthcare provider who ordered the bloodwork as they have the benefit of knowing the reason for the bloodwork, the type of tests ordered, and the patients medical history. As such, they will be in the best position to offer this guidance for each individual situation.

    The Vaccine Testing Process

    The development cycle of a vaccine, from lab to clinic.

    PRECLINICAL TESTING: Scientists test a new vaccine on cells and then give it to animals such as mice or monkeys to see if it produces an immune response.

    PHASE 1 SAFETY TRIALS: Scientists give the vaccine to a small number of people to test safety and dosage, as well as to confirm that it stimulates the immune system.

    PHASE 2 EXPANDED TRIALS: Scientists give the vaccine to hundreds of people split into groups, such as children and the elderly, to see if the vaccine acts differently in them. These trials further test the vaccines safety.

    PHASE 3 EFFICACY TRIALS: Scientists give the vaccine to thousands of people and wait to see how many become infected, compared with volunteers who received a placebo. These trials can determine if the vaccine protects against the coronavirus, measuring whats known as the efficacy rate. Phase 3 trials are also large enough to reveal evidence of relatively rare side effects.

    EARLY OR LIMITED APPROVAL: Many countries have procedures for providing emergency authorizations for vaccines, based on preliminary evidence that they are safe and effective. In addition, some countries such as China and Russia began administering vaccines before detailed Phase 3 trial data was made public. Experts have warned of serious risks from jumping ahead of these results.

    What Is The Difference Between Tts And Cvst

    Thrombosis with thrombocytopenia syndrome, or TTS, is the name that has been given to the condition identified in a small number of individuals after receipt of the COVID-19 J& J/Janssen or AstraZeneca vaccines. TTS is distinct from cerebral venous sinus thrombosis, or CVST, because in TTS not all of the clots are associated with the large vessels of the brain. Some individuals had clots in their lungs, heart, intestines, spleen, or large blood vessels in their legs. However, CVST was originally used, and may still be used to refer to the condition by some individuals, because the original cases closely resembled this previously defined condition.

    Safety And Side Effects

    Fact check: Why are there so many COVID vaccination breakthroughs? | DW News

    The COVID-19 vaccines currently approved have been thoroughly reviewed by the Medicines and Healthcare products Regulatory Agency in the UK . The regulatory team have completed a full review of the safety information reported from the trials, which includes several months follow-up data from 23,000 people for the Oxford-AstraZeneca vaccine, 44,000 people for the Pfizer-BioNTech vaccine and 30,000 people for the Moderna vaccine.

    This means that the MHRA has reviewed all the information from the clinical trials of these vaccines, which includes assessing all the side effects and medical conditions that people in the trials experienced.

    The number of illnesses reported in the vaccinated group is compared with the control group, to see whether the vaccine could be associated with an increase in any medical conditions. The rates of illness are also compared with the rate of those illnesses in the general population. For any severe illnesses reported, a specialist doctor involved in treating the person and an independent safety committee consider whether the illness could be associated to the vaccine.

    All the information about adverse events reported during the trial has been provided to the regulators, and the safety profile of COVID-19 vaccines is similar to that of other vaccines.

    How Well Does The Covid

    The clinical trial measured two things to evaluate how the vaccine worked:

  • Disease While 18 participants in the placebo group got COVID-19 at least seven days after having the second dose of the vaccine, none in the vaccinated group were infected. This represents 100% efficacy. In the 5- to 11-year-old group, three vaccinated children got COVID-19 compared with 16 children in the placebo group this represents a 90.7% efficacy.
  • Immune response Now that we know what antibody levels adults experience following vaccination, studies can compare the levels in other groups to see if the vaccine works as well. These are often referred to as non-inferiority studies, meaning the vaccine is being tested in the study group to make sure it works at least as it does in another group previously studied. In the Pfizer study, average neutralizing antibody responses were similar in 5- to 11-year-olds compared with older children and young adults even though the dose was lower. While we still do not know if a certain level of virus-neutralizing antibodies indicates that an individual is protected against infection, we can be confident that vaccinated children respond equally well compared with older children and young adults.
  • Vaccinated But Still Hesitant

    One peculiar phenomenon that has developed out of this recent landscape is that some people have started looking for information on how to detox from the vaccine after they have received it, particularly if they had not wanted to have it in the first place.

    A TikTok video featuring claims that people who had had the COVID-19 vaccine should take complex detox baths, containing, among other things, borax, hit the headlines in November. However, that video was not the only example of emerging claims that people should detox from the vaccine to avoid unwanted side effects.

    Suggestions for detoxes after receiving a COVID-19 vaccine ranged from borax baths to detox diets. Suggested detox diets included high fat diets to bind the toxins in the vaccines, alongside supplements, including zinc and vitamins C and D.

    According to some media reports, some even suggested cupping the site of the injection to remove the vaccine.

    More extreme claims suggest that people who have had the vaccine need to take a prophylactic dose of ivermectin and hydroxychloroquine to counteract what they believe to be a negative impact of the vaccine on their immune system. The FDA does not authorize the use of hydroxychloroquine to combat COVID-19 but rather advises against using ivermectin for this purpose.

    She added that while there is a lot of anger in the U.S. towards people who are not vaccinated, she just feels sadness about the situation:

    In the U.S. women between 30 and 49 years of age have most often been affected by this condition compared with other groups however, both men and women between 18 to 64 years of age have been affected.

    Data regarding the race of all affected in the U.S. have not been shared, but at the time of the pause, those which were known were White. With this said, a large percentage of the recipients of the J& J vaccine at the time of the pause had also been White , so there is no reason to think that people of other races would be exempt from this side effect.
