The Qdenga vaccine, which works against Dengue, is experiencing shortages in the country and this is a threat for the summer, in which cases are expected to be more than the previous one. It is available under two pharmaceutical presentations: those that go to the private sector, which arrive in a prefilled syringe, and those that go to the public system that are delivered in a vial. In such a context, some questions arise about the future of its application.
Some questions about the lack of vaccines against Dengue
1- Why are there a lack of vaccines?
The doses are missing in almost all pharmacies and this problem is due to the fact that demand exceeds production. In addition, stock is limited in vaccination centers. At the moment, there is no certain date for delivery again, according to officials from a pharmaceutical chain. Clarion. They admit the same from the Argentine Pharmaceutical Confederation (COFA).
Laboratory supplies Takeda They do not rule out that, for the public or private sphere, “this unusual level of demand exceeds the most optimistic forecasts.” They also say they are expanding manufacturing facilities to increase production capacity.
“The goal is to manufacture 100 million doses per year by the end of the decade,” they emphasize. The fact may represent a obstacle for members of certain social and prepaid works who are guaranteed coverage only in pharmacies.
2- Is the second dose guaranteed for those who received the first dose at a pharmacy or another vaccination center?
Although it is not necessary to apply the second dose in the same establishment, in several laboratories decided to prioritize those who gave the first injection in that same place for a matter of “consumer service”.
3- I gave myself the first dose: how long does it take before I can take the second dose?
The scheme is completed with 2 subcutaneous applications that respond to the same formula, with a minimum interval of three months between each. Complete protection against dengue is acquired ten days after the second application.
“The fact that the other puncture arrives 4 or 5 months after receiving the first one is not of great importance. In general, The second dose stabilizes, stimulates, harmonizes and prolongs the antibodies over time. Although it is not ideal, it is not a problem because the immunological memory preserves the defenses,” said the infectious disease specialist. Hugo Pizzi to the newspaper.
One in five cases of Dengue is associated with climate change
A study revealed that one in five cases of this disease can be linked to climate change. In detail, the researchers stated that “19% of current dengue cases can be linked to climate change” because, with rising temperatures, the area in which mosquitoes transmit diseases expanded.
Additionally, the study warned that this ecological problem has the potential to cause a 40% to 60% increase in the disease by 2050, with an increase in cases of between 150% and 200% in some areas.
