The World Health Organization (WHO) warns of a vaccine syringe shortage in 2022
As the supply of COVID-19 vaccines is improving, the supply of immunization syringes needs to keep pace warned the World Health Agency today. It raised concerns of a possible deficit of one to two billion immunization syringes in 2022 which would then lead to serious problems such as slowing down immunization efforts.
Speaking at a news briefing at the United Nations in Geneva, Lisa Hedman, Senior Advisor for Access to Medicines and Health products at the World Health Organization (WHO ) said that “a shortage of syringes is unfortunately a real possibility and here are some more number: with the global manufacturing capacity of around six billion per year for immunization syringes, it is pretty clear that a deficit in 2022 of over a billion could happen if we continue with ‘business as usual’”.
Due to the number of injections being given to respond to the pandemic, shortages of syringes for the full safety for patients and health care workers should be avoided.
“There have already been more than 6.8 billion doses of Covid-19 vaccines administrated globally”, according to Ms. Hedman. “Now, to give you a comparison, this is nearly double the number of routine vaccinations that are given per year which, of course, means double the number of immunization syringes”.
Poorer countries that often place small orders and hence don’t have priority with manufactures, could be particularly affected. The WHO is calling on countries to plan ahead and order in large amounts to give manufacturers some lead time.
Syringes also require special logistics as “they are particularly impacted by transportation problems because they are large. A syringe takes up ten times more space in transportation than a dose of a vaccine”, stated WHO’s Ms. Hedman.
Syringes for vaccinations cannot be used for other purposes and they have a mechanism which ensures they are used only once. A potential risk of a lack of syringes might be the very unsafe practice of reusing syringes and needles, fears the WHO.
“One serious result of a shortage could be delays in routine immunizations and other healthcare services and so here were talking about the injections that we give as part of normal health care”, said Ms Hedman. “Now it could have a public health impact for years to come if we have a generation of children who don’t receive their childhood vaccinations”.
Syringes are manufactured on every continent with India and China being the largest exporting countries.
With a looming syringe shortage, the global coordination efforts of the COVAX facility – a collaboration of governments, global health originations, manufactures, scientists, private sector and civil society aiming to provide equitable access to Covid-19 treatment and vaccines – will now ensure that syringes are available together with the vaccine.
“If we are promoting equity in making vaccines available to the world and we are promoting equity to make vaccines available, then we have to do the same with the syringes,” said Ms. Hedman.
According to WHO estimates, 16 billion injections are given worldwide in a normal year. Before the pandemic, vaccinations accounted for 5-10 per cent of that, or up to 1,6 billion. With the Covid-19 pandemic, an addition 6,8 billion doses now have been given worldwide.

New data showing that rivers were at their lowest level for decades last year provides further evidence that the climate crisis is real and countries must act immediately to protect themselves from the increasing threat to communities and livelihoods, the UN World Meteorological Organization (WMO) said on Thursday.
The key findings from WMO’s State of Global Water Resources 2025 report covering the hydrological cycle and extreme events in the five-year period to last year:
Highlighting the long-term decline in the Earth’s freshwater storage and glacier melt, WMO Secretary-General Celeste Saulo explained that the planet’s water reserves used to act as a planetary “savings account” that absorbed the occasional dry season, avoiding a water crisis. “One of the central stories of the 2025 report is what is happening to that savings account? And the simple answer is that we are depleting it,” she told journalists in Geneva.
Groundwater reserves are equally stretched and have been in decline since 2014, WMO’s report states, with nearly two-thirds of monitored wells worldwide showing levels lower than the historical norm and indicating a shift “further toward deficit…not recovery”.
“At the same time, we are seeing more water-related disasters,” Ms. Saulo said, while also stressing that the currently strengthening El Niño “will increase the risk of drought in some areas, and flooding in others”.
Glaciers disappearing
In 2025, for the fourth consecutive year, every major glaciated region on Earth lost ice mass, leading to short-term hazards including floods and long-term water insecurity, according to WMO.
Responding to a question about whether the changing global water cycle might have contributed to the deadly Nepal-China flooding disaster, Ms. Saulo explained that melting ice and rock was just one factor in the chain of events that ultimately sent a massive and deadly wall of water and debris downstream on 26 August, killing at least 1,367 people.
“You asked if it could happen again? Absolutely; the problem in this region is that there’s 63,700 glaciers at the last count,” she told a Press Conference in Geneva. “Even if you’re looking with remote sensing with satellites at these glaciers, you might see some faults, you might see some slight shifting, that does not mean necessarily catastrophic collapse. So, in order to plan for this, it’s very, very difficult. But the international community is looking very hard at ways in which we can bring people together to solve some of these monitoring issues.”
Data indicates that glaciers shrank between 2023 and 2025 with cumulative losses of 1,400 gigatonnes of water – or about one third of annual fresh water needs.
Every major glacier region on Earth lost ice for the fourth consecutive year.
“All 19 glacier regions around the globe lost ice; in Central Asia, Iceland, the Russian Arctic and western Canada and the United States, it was among the three worst years on record,” said Wayne Jenkinson, WMO’s Director of Hydrology and Cryosphere.
Some regions with smaller glaciers such as Central Europe, the Caucasus, the western Canada and the United States may already have reached “peak water”, Mr. Jenkinson warned.
“After this point, the glacier gives less meltwater each year simply because there is less ice left to melt. That matters for every community downstream that relies on water during hot, dry summers,” he explained.
Narelle van der Wel, WMO’s Head of Cryosphere Monitoring, Predictions and Services, stressed that while some further glacier loss is unavoidable, the eventual scale of the decline is not predetermined.
“Some glacier loss is inevitable, but total loss of glaciers is not yet inevitable,” she said, pointing to emissions reductions as central to limiting future losses.
Preparing for moving baselines
The report does not attribute every observed change to climate change alone. WMO says pressure on water resources and natural variability also contribute.
Mr. Jenkinson said governments need to prepare for “moving baselines” as historical patterns become less reliable.
“The situation 30 years ago is not where we are today,” he said. Countries, he added, need to prepare “for those changes that have really already arrived”.
