The Therapeutic Goods Administration (TGA) is the medicine and therapeutic regulatory agency of the Australian Government. As part of the Department of Health and Aged Care, the TGA regulates the quality, supply and advertising of medicines, pathology devices, medical devices, blood products and most other therapeutics. Any items that claim to have a therapeutic effect, are involved in the administration of medication, or are otherwise covered by the Therapeutic Goods Act 1989, the Therapeutic Goods Regulations 1990, or a ministerial order, must be approved by the TGA and registered in the Australian Register of Therapeutic Goods.
The Joint Committee on Vaccination and Immunisation (JCVI) is an independent expert advisory committee that advises United Kingdom health departments on immunisation, making recommendations concerning vaccination schedules and vaccine safety. It has a statutory role in England and Wales, and health departments in Scotland and Northern Ireland may choose to accept its advice.
The Oxford–AstraZeneca COVID‑19 vaccine, sold under the brand names Covishield and Vaxzevria among others, is a viral vector vaccine for the prevention of COVID-19. It was developed in the United Kingdom by Oxford University and British-Swedish company AstraZeneca, using as a vector the modified chimpanzee adenovirus ChAdOx1. The vaccine is given by intramuscular injection. Studies carried out in 2020 showed that the efficacy of the vaccine is 76.0% at preventing symptomatic COVID-19 beginning at 22 days following the first dose and 81.3% after the second dose. A study in Scotland found that, for symptomatic COVID-19 infection after the second dose, the vaccine is 81% effective against the Alpha variant and 61% against the Delta variant.
The Pfizer–BioNTech COVID-19 vaccine, sold under the brand name Comirnaty, is an mRNA-based COVID-19 vaccine developed by the German biotechnology company BioNTech. For its development, BioNTech collaborated with the American company Pfizer to carry out clinical trials, logistics, and manufacturing. It is authorized for use in humans to provide protection against COVID-19, caused by infection with the SARS-CoV-2 virus. The vaccine is given by intramuscular injection. It is composed of nucleoside-modified mRNA (modRNA) that encodes a mutated form of the full-length spike protein of SARS-CoV-2, which is encapsulated in lipid nanoparticles. Initial guidance recommended a two-dose regimen, given 21 days apart; this interval was subsequently extended to up to 42 days in the United States, and up to four months in Canada.
The COVID-19 vaccination programme in the United Kingdom is an ongoing mass immunisation campaign for coronavirus disease 2019 (COVID-19) during the COVID-19 pandemic in the United Kingdom.
The COVID-19 vaccination program in the Philippines was a mass immunization campaign against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), in response to the pandemic in the country. The vaccination program was initiated by the Duterte administration on March 1, 2021, a day after the arrival of the country's first vaccine doses which were donated by the Chinese government.
SARS-CoV-2, the virus that causes COVID-19, was isolated in late 2019. Its genetic sequence was published on 11 January 2020, triggering an urgent international response to prepare for an outbreak and hasten the development of a preventive COVID-19 vaccine. Since 2020, vaccine development has been expedited via unprecedented collaboration in the multinational pharmaceutical industry and between governments. By June 2020, tens of billions of dollars were invested by corporations, governments, international health organizations, and university research groups to develop dozens of vaccine candidates and prepare for global vaccination programs to immunize against COVID‑19 infection. According to the Coalition for Epidemic Preparedness Innovations (CEPI), the geographic distribution of COVID‑19 vaccine development shows North American entities to have about 40% of the activity, compared to 30% in Asia and Australia, 26% in Europe, and a few projects in South America and Africa.
The general COVID-19 vaccination in Australia program began on 22 February 2021 in response to the COVID-19 pandemic, with the goal of vaccinating all willing people in Australia before 2022. Front-line workers and aged care staff and residents had priority for being inoculated, before a gradual phased release to less-vulnerable and lower-risk population groups throughout 2021. The Therapeutic Goods Administration (TGA) approved four vaccines for Australian use in 2021: the Pfizer–BioNTech vaccine on 25 January, the Oxford–AstraZeneca vaccine on 16 February, Janssen vaccine on 25 June and the Moderna vaccine on 9 August. Although approved for use, the Janssen vaccine was not included in the Australian vaccination program as of June 2021.
The COVID-19 vaccination programme in the Republic of Ireland is an ongoing mass immunisation campaign that began on 29 December 2020 in response to the COVID-19 pandemic in the Republic of Ireland. Ireland's vaccination rollout has been praised as one of the most successful rollouts in the world and was ranked number one in the European Union in terms of its percentage of adult population fully vaccinated, and was also ranked number one in the EU for the number of booster vaccines administered.
COVID-19 vaccination in Canada is an ongoing, intergovernmental effort coordinated between the bodies responsible in the Government of Canada to acquire and distribute vaccines to individual provincial and territorial governments who in turn administer authorized COVID-19 vaccines during the COVID-19 pandemic in Canada. Provinces have worked with local municipal governments, hospital systems, family doctors and independently owned pharmacies to aid in part, or in full with vaccination rollout. The vaccination effort in full is the largest such immunization effort in the nation's history. The vaccination effort began December 14, 2020, and is currently ongoing.
The COVID-19 vaccination program in Colombia is an ongoing effort of mass immunization put in place by the Colombian government in order to respond to the ongoing COVID-19 pandemic. The virus causing COVID-19 was confirmed to have reached Colombia on 6 March 2020. Colombia's preparation and readiness for a vaccine program allowed it to join the first group of countries who received vaccines through COVAX. The first vaccine in Colombia was given to a nurse on 17 February 2021.
The National Advisory Committee on Immunization is an advisory body that provides the Government of Canada with medical and scientific advice relating to human immunization.
Post-vaccination embolic and thrombotic events, termed vaccine-induced immune thrombotic thrombocytopenia (VITT), vaccine-induced prothrombotic immune thrombocytopenia (VIPIT), thrombosis with thrombocytopenia syndrome (TTS), vaccine-induced immune thrombocytopenia and thrombosis (VITT), or vaccine-associated thrombotic thrombocytopenia (VATT), are rare types of blood clotting syndromes that were initially observed in a number of people who had previously received the Oxford–AstraZeneca COVID‑19 vaccine (AZD1222) during the COVID‑19 pandemic. It was subsequently also described in the Janssen COVID‑19 vaccine, leading to the suspension of its use until its safety had been reassessed. On 5 May 2022 the FDA posted a bulletin limiting the use of the Janssen Vaccine to very specific cases due to further reassessment of the risks of TTS, although the FDA also stated in the same bulletin that the benefits of the vaccine outweigh the risks.
The COVID-19 vaccination campaign in Quebec is an ongoing provincial effort to distribute and administer vaccines against COVID-19.
